After reading the article [dgl.com], the solution looks pretty obvious.

The Riemann hypothesis asserts that all interesting solutions of the equation z(s) = 0 lie on a straight line.

Well, graphing s versus z(s), if z(s) is always zero, then obviously all values of s solving that equation lie on the s axis, which is a straight line. QED.

No, silly rabbit! They don't mean a straight line in the {z(s), s} coordinate plane, they mean a straight line in the {s.r, s.i} coordinate plane.

I.e., s, which is a complex number, has two parts - a 'real' part and an 'imaginary' part. Thus, z(s) for any complex s returns zero - according to this proof - if s.r (the 'real' part) and s.i (the 'imaginary' part) lie along a certain straight line.

A proof of the Riemann's hypothesis (RH) about the non-trivial zeros of the Riemann zeta-function is presented.

We are going to show you beyond a shadow of a doubt that the non-trivial zeros of the zeta-function are of the form 1/2 +- i*theta_n.

It is based on the construction of an infinite family of operators D^{(k,l)} in one dimension, and their respective eigenfunctions \psi_s (t), parameterized by continuous real indexes k and l.

To do this, we are going to use the operators D^{(k,1)} and their respective vectors \psi_s (t), such that using D^{(k,1)} on \psi_s (t) will produce k*(\psi_s (t)), where k is some non-zero constant. Unfortunately though, we have to show a way to product all of these operators. So the "construction of" the operators will be contained within the proof.

Orthogonality of the eigenfunctions is connected to the zeros of the Riemann zeta-function.

These \psi_s (t) vectors are also all at "right-angles" to eachother. So their cross products = 0.

Due to the fundamental Gauss-Jacobi relation and the Riemann fundamental relation Z (s') = Z (1-s'), one can show that there is a direct concatenation among the following symmetries, t goes to 1/t, s goes to \beta - s (\beta a real), and s' goes to 1 - s', which establishes a one-to-one correspondence between the label s of one orthogonal state to a unique vacuum state, and a zero s' of the \zeta.

Z(s') = Z(1-s') is true. Thus, we can show that there is a connection between the follwing symmetries:
t goes to 1/t,
s goes to \beta -s (where beta is a real number),
and s' goes to 1 - s'

In Q.M. we can show then a correspondence between one of these orthogonal states to a unique vacuum state (from Quantum Mechanics), and thus a solution of the zeta function.

It is shown that the RH is a direct consequence of these symmetries, by arguing in particular that an exclusion of a continuum of the zeros of the Riemann zeta function results in the discrete set of the zeros located at the points s_n = 1/2 + i \lambda_n in the complex plane.

From these neat little tricks, we can show that the Riemann Hypothesis must be true, because these things are true.

The arXiv will post nearly anything that resembles a mathematical paper-they don't do any refereeing. However, they apparently use the "general mathematics" section for papers that seem crankish like this one. And the fact that it took more than six months for this proof to make the news is proof that absolutely no one reads that section.

I haven't looked at the proof yet, but I'm worried that it will be at best a "physicist's proof"-a series of claims deduced by using some sort of physical reasoning that is not mathematically rigorous, since it seems to have been written by physicists, and is in the physics section.

Noone I know (mathematicians, that is) have bothered to read beyond the point where they throw their hands up in the air and cry "this is nothing but sloppy handwaving".

For example, in the _very first_ equation, he introduces an "operator", and conveniently forgets to mention what space this operator is supposed toact on. A Banach space? A Hilbert Space? We should not have to _guess_ what algebraic structure they're using.

Classical Math Problem May Be Solved

One of the great unsolved problems of mathematics, the so called Riemann Hypothesis, may have a solution 144 years after Bernhard Riemann published his idea of a special equation, related to prime numbers.

If the proof does turn out to be correct, the two problem solvers may be eventually be able to collect a one million dollar reward.

In the year 1900, the world's leading mathematicians gathered for a conference in Paris. During the conference, David Hilbert, the leading mind of mathematics at the time, presented 23 problems which would affect mathematics for the ensuing century, and yet today. One of these problems was the Riemann hypothesis, and despite great effort it has remained unsolved. However, in November of 2002, Carlos Castro of Clark Atlanta University, Atlanta, USA, and Jorge Mahecha of the University of Antioquia, Medellin, Colombia published a proposed solution.

They won't be able to collect the one million dollar reward offered by the american Clay Mathematics Institute until one year after publication. This is to allow other mathematicians time to check the result, and verify its correctness.

- If this is true, then it is a sensational. This is a class of problems which requires much work before a possible solution can be confirmed. Thousands of mathematicians all over the world will cast themselves at this, and examine the evidence in minute detail, says Anders Karlqvist, mathematician, professor of informatics and head of the Polar Research Secretariat.

He explains that certain of Hilberts problems are problem areas rather than individual problems. Some have also been reformulated. If the Riemann Hypothesis is solved, then ten of the 23 problems are solved, seven are unsolved, five are partially solved, and one is no longer relevant.

According to Anders Karlqvist, Hilbert was a great man within his field, and a great period ended with him. He was the last man to have an overview of all the fields of mathematics.

Mathematics have developed very rapidly during the latest decades, thanks to an aid that the mathematicians of the early 20th century couldn't predict - the computer. The ever faster and larger computers of today can handle vast quantities of numbers and quickly make calculations that used to be impossible for a person even if he or she spent an entire lifetime.

With the help of computers, certain problems have been solved, such as the four color problem. It says that at most four different colors are neccessary to colour a map, so that areas with a common border don't have the same color. A computer program has systematically gone through all possible combinations.

Anders Karlqvist thinks that this involves a philosophical dilemma: should proofs in the form of computer programs be accepted? He believes that we stand before a culture shift within mathematics. During the coming decade mathematics will develop radically due to the increasingly efficient computers.

There is a saying sometimes employed by cruel mathematicians to describe illucid 'proofs': "This isn't right. This isn't even wrong."

Having said that, it surely would be nice to see 'exactly where it goes wrong'. For simple arguments a standard "the first error is on page t, line s" will suffice. More convenient is to find a claim to which an explicit counterexample can be constructed, that is, to show that the proof (if valid) leads to a contradiction - of course this works best when the proof is not reductio ad absurdum :-P

Finally, we should always remember that the burden of "proof" is on the "prover" - it's not anyone else's responsibility if the paper isn't even written in what we'd call mathematics. (Naturally it has no chance of being published in a print journal if it's in that state, which is a necessary condition for the awarding of the prize.)

(The rest is a slightly tangential discussion of two common problems arising from extremely imprecise methods, aka "handwaving".)

Here's a gratuitous example:

Prop. There are more real numbers than integers.
"Proof." Consider the interval [n,n+1) for arbitrary integer n. In this interval there is one integer, but a slew of reals, eg, n+1/2, n+pi/4, and so forth. So, there are more reals than integers.

Of course this proposition is true but the proof is nonsense, since we can "derive" by mimickery

Prop. There are more rational numbers than integers.

which is just false.

This is a pretty simplistic example and doubtless the author of the purported proof of RH is using much more sophisticated handwaving, for which I'll produce another analogy:

Prop. 2 has no proper factorisation.
"Proof." The only integers dividing 2 are 1, -1, 2, -2, the former two being units and the latter two the number and an associate.

This proposition falls into the "not even wrong" category. Why? -- because to write down the word "factorisation" begs the question: in what ring (ie, algebraic context)? Absolutely, 2 is irreducible in the integers. But not in the Gaussian integers:

Prop. 2 is not irreducible in the Gaussian integers.
Proof. We see easily that 2 = (1+i)(1-i). Each factor of the RHS has norm 2, so neither is a unit, and in fact 1+i is a Gaussian prime, and 1-i = (-i)(1+i) is also a Gaussian prime.

The error in the first proposition about 2 was that it made no reference to the context of the discussion. This is the sort of handwaving that occurs in the "proof" of RH. We can see it really makes a difference - in one context the prop. was true, and in another false; sometimes even to utter the word "factorisation" is to already condemn oneself to the "not even wrong" bin.

Context is everything. And in the absence of meaningful context, assume the most simple meaning of factorisation is intended, i.e. decomposition into plain vanilla positive real integers.

Not specifying context is by itself not necessarily an error. It's just sloppy writing, and makes the proof harder to read (the reader has to figure out what exactly is meant). Not specifying context only becomes an error if you start mixing to contradictory meanings. For example, if in your "factorization of 2 problem", you start two lines of reasoning, one in which you limit yourself to integers, and one in which you allow complex numbers.

A smart reader (and who also has lots of time on his hands...) may check out the proof by trying out the various possible contexts. Either he finds one context where the whole proof makes sense, or he does indeed find an incorrect mixing ("on page 10, the authors work in the algebraic context of simple integers, while on page 15 they work in the context of Gaussian integers"). Of course, the problem here is that the thing is so sloppily written, with so many underspecified contexts that nobody is really willing to invest any time debugging it...

Definition of the zeta function: There is something called Riemann's zeta function: it is a function of a single complex variable. It is defined as zeta(z) = 1^(-z)+2^(-z)+3^(-z)+... (ad infinitum) You can easily see that zeta(z), as defined, converges if and only if Re(z)>1 (real part of z). However, the function is defined for all complex z using something called the analytic continuation: basically there is a unique way to extend zeta(z) for re(z) < 1 in such a way that derivatives of all orders exist at all points.

The hypothesis states that all (nontrivial) zeroes of the zeta function occur on the line Re(z) = 1/2.

If proved, it has immense implications in many areas of pure and applied mathematics. For instance, in number theory: it would say a lot about the distribution of prime numbers.

The stature of the problem can be seen from the fact that it was one of the 23 problems which would shape the mathematical progress of the 20th century that David Hilbert drew up in his lecture at the 1900 Paris congress of mathematicians.

If you can't explain something in ordinary words to a layman, then you really don't understand it.

I'm about halfway through writing up my PhD thesis on some applications of homological algebra to knot theory and low-dimensional geometric topology (provisional title liber rerum dementiae, but it'll probably end up being called something more mathematically appropriate).

In principle, yes, I could explain the details of my research to a suitably motivated layman. But I suspect it would take rather a long time.

You see, and this really isn't meant to sound arrogant, supercilious, or dismissive, university-level mathematics is pretty damned difficult, and the details of most cutting-edge research really doesn't make sense until you've spent several years learning the background (the mindset, the language, the fundamental concepts).

My current area of research is essentially the applications of homological algebra to knot theory and low-dimensional geometric topology. To explain this to a non-mathematician, I'd first have to teach them a lot of background stuff (group theory, a bit of stuff about rings and modules, point set topology, basic algebraic topology (the fundamental group, (co)homology theory), some geometric topology (basic course in knot theory, some stuff about 3-manifolds), a bit of category theory, and some homological algebra (broad overview of the (co)homology theory of groups and algebras)).

It's taken me nearly nine years (3-year BA, 1-year MSc specialising in topology and knot theory, plus nearly five years doing a (part-time) PhD) to get to this point myself. If I were a bit cleverer (or didn't have a proper' job as well) I might have been able to shave a couple of years off that.

My friend Steve has a physics degree. I managed, in ten minutes one evening, with much handwaving, to give him some idea of what my thesis is all about. It helped that he knew what a group was already though. But for me to explain it fully to him would probably necessitate him doing at least one mathematics degree first. And that's not really something I'd wish on one of my friends :)

Now this really isn't meant in an arrogant way, and I hope you won't read it like that, but Euclid was right: There is no royal road to geometry.

I can have a go at explaining the Riemann hypothesis, though. To fully understand what it's about and why it's so damned difficult you'll need to do an advanced course in complex analysis (which isn't my field either).

A complex number is a sort of two-dimensional number, which you can regard as a point in a plane (the complex plane' or argand diagram'). You add them together coordinate-wise, and you multiply them together in a weird manner which involves something which behaves like a square root of -1' (engineers also like to think of it as a sort of 90-degree phase-shift operator, I'm told).

There's a particular function (Riemann's zeta function') defined on the complex plane (it takes one complex number as input and returns one complex number). For some complex numbers (the zeros of the function'), the value of this function is zero.

The trivial' zeros occur at the points -2, -4, -6, ... on the horizontal axis.

The non-trivial' zeros (that is, all the other points for which zeta is zero) all seem to occur on the line parallel to the vertical axis that intersects the horizontal axis at +0.5. Indeed, nobody's ever found one which doesn't.

The Riemann Hypothesis is that *all* the non-trivial zeros lie on this line. It's known to be true for the first (large number which temporarily escapes me), but it turns out to be phenomenally difficult to prove that it's true in every case.

Now that's the basic idea, but it doesn't (and I can't - it's not my field) explain *why* it's so difficult that some of the greatest minds (Hardy, Littlewood, Ramanujan, etc) of the past 150 years have failed to prove it, and why the Clay institute are willing to pay a million dollars to someone who can.

The Middle English spellings of prove included preven, a form that died out in England but survived in Scotland, and the past participle proven, a form that probably rose by analogy with verbs like weave, woven and cleave, cloven. Proven was originally used in Scottish legal contexts, such as The jury ruled that the charges were not proven.

I know the editors of this site mean well, but what we have here is a link to a site that defines the Riemann Hypothesis in very abstract terms, a link to a LANL preprint from two completely unknown researchers deposited there in November 2002, and a link to an obscure Swedish newspaper from almost two weeks ago, and no other supporting material. So my BS meter is running at 5.

The odds that "this is the one!" given that pedigree would seem to be really tiny. But the clincher for me is the following web page dedicated to would-be proofs of the Riemnann Hypothesis [ex.ac.uk] whose important text is (and I quote):

If you are a university mathematics lecturer who teaches analytic number theory, you might want to consider setting your students the task of deconstructing the more serious of these. They may otherwise never be given any serious attention, which would be a shame.

And the Castro and Mahecha preprint (and another grandiosely titled preprint by Mahecha) is linked to from there. Now my BS meter is running at about 9. So now I check for messages abou this at deja.com in the sci.math group. [google.com] Read the thread yourself; it's pretty entertaining.

So, with my BS meter running at 11, the work having been submitted for coming up on 6 months, and no indication whatsoever that this is real, I suggest it is false.

And I also suggest that Slashdot might wish to consider contacting a real mathematician to filter their potential stories on mathematics, since I can't tell you the last time one of these "is X finally proven?" stories has panned out.

While I have no doubt that SvD is of singular value to almost everybody (especially for its largest entries on the diagonal), the fact is that it comes from Sweden makes it orthogonal to our concerns. (Sorry about that...)

Actually, the discussion basically says that nobody could read the thing and that it was chock full of typos. Once again, if I had a proof of the Riemann Hypothesis, I would probably make very certain that it was free of such interest-busting material. A mathematician can feel free to correct me, but I am assuming that while raw papers (especially from non-native speakers of the language the paper is submitted in) can be tough to get through, you usually *do* detect the high quality of the real work at some point pretty early on, and if you don't, you assume the worst.

If you mean to say that the reason that the rest of the media isn't catching on is that the only story so far has been in a Swedish newspaper, I don't object. But if you're saying that being run in a non-US newspaper makes the story less likely to be true, I think you are a little confused.

Recently, as in the last couple of years, the most promising contributions to RH related stuff has come from high energy physics, and many people, both in math and in physics, believe that this is the approach that will eventually bear fruit. If indeed a final proof would be more physics than number theory (perhaps the proof of the RH would only be a corrollary of some completely un-number theoretic line of reasoning) wouldn't it be reasonable to publish it in a physics journal? That it has implications for number theory isn't enough of a reason to publish it in a number theoretical journal, mostly because the readers of it would not be able to determine whether it was correct or not.

They know flaws will be detected, and they know that they would never win any prize with an unsound proof.

But, like I said (in the write up, even), there is a clear possibility that this isn't the real thing. I only think you're overstating your case.

It isn't, except that it is. The problem I have here is with accepting "generally trustworthy" as a blanket statement that applies equally to things we know newspapers are usually pretty good at (politics, current issues, scandals, crimes, and the like) and areas where we (or at least I) do not have high confidence in their abilities. High-level mathematics clearly falls into the second category; I am not certain I would trust *any* newspaper account of this. Fort that matter, I can get specific here. The translation of the article you pointed us to includes this:

One of these problems was the Riemann Hypothesis, and despite great efforts it has remained unsolved. But in November 2002 Carlos Castro from Clark Atlanta University, Atlanta, USA, and Jorge Mahecha from the University of Antioquia, Medellin, Columbia, offered a solution.

Now, the problem here is that some random author or another submitting a paper that claims to solve an important math problem like this is really not newsworthy. It really does happen almost all of the time, and yet the writer of this story seems to be innocent of this fact. Indeed, if the author had asked for comment or advice from any mathematician about this particular attempt, I'm sure the answer would have been "we see five or six of these a year". Actually, the fact that this is a *good* newspaper makes the point even more strongly: despite their expertise, they really didn't know how to evaluate this as a news story. That's the problem.

True enough, but see below, and the fact that if *I* had a proof of the Riemann Hypothesis, I probably wouldn't submit it to the high energy physics and "general math" sections of xarchiv.

OK, now that's interesting, and I did not in fact know that. And there is no question that new lines of attack can come from unusual places. I do feel that these new lines often offer themselves up in somewhat more propitious circumstances. So if a high energy physicicst had teamed up with an important number theorist to do the paper, and it was based on the kind of insight that is taken for granted in one community but not the other (e.g., "interesting; in our work we rewrite the integral *this* way and then prove these bounds...")

Unfortunately, the Clay Math Prize has kind of made proving the Riemann Hypothesis a "make-money-fast" scheme.

They know flaws will be detected, and they know that they would never win any prize with an unsound proof.

Well, the term "amateur" is always a relative thing. So it would be easy to see why a non-famous high energy physicist might spend a lot more time on something like RH after the prize money is publicized given that the chances of hitting on this or on any round of funding these days in physics might be the same lottery odds. :-( So a detectable number of physicists entered the field of cognitive neuroscience when the SSC went down, not necessarily for the big bucks, but to try and work on a challenging problem where there was some hope of funding. Results were mixed.

Plus, I can report that a couple of definitely professional mathematicians I have met do (prviately) admit that the Clay Prize money has actually attracted their attention to the prize problems, if only just to take a brief whack at them and see if anything new falls into place.

But, like I said (in the write up, even), there is a clear possibility that this isn't the real thing. I only think you're overstating your case.

I have pretty high confidence that the current attempt has basically already joined all of the other failed attempts. There are so many of these, and this does share many disturbing similarities with them. Thanks for your comments, though; I really had no idea that high energy physics had any implications for RH until I read your post.

Everybody's favorite was the Goldbach conjecture, with the twin prime conjecture coming in a close second.

It is based on the construction of an infinite family of operators D^{(k,l)} in one dimension, and their respective eigenfunctions \psi_s (t), parameterized by continuous real indexes k and l. Orthogonality of the eigenfunctions is connected to the zeros of the Riemann zeta-function. Due to the fundamental Gauss-Jacobi relation and the Riemann fundamental relation Z (s') = Z (1-s'), one can show that there is a direct concatenation among the following symmetries, t goes to 1/t, s goes to \beta - s (\beta a real), and s' goes to 1 - s', which establishes a one-to-one correspondence between the label s of one orthogonal state to a unique vacuum state, and a zero s' of the \zeta. It is shown that the RH is a direct consequence of these symmetries, by arguing in particular that an exclusion of a continuum of the zeros of the Riemann zeta function results in the discrete set of the zeros located at the points s_n = 1/2 + i \lambda_n in the complex plane."
