Anthropic says research Claude advanced a problem related to the Riemann hypothesis

Anthropic says an unreleased research version of Claude raised a proven lower bound for the share of Riemann zeta zeros on the critical line from about 41.6% to 67.2%. The claim is not a proof of the Riemann hypothesis and is not independently verified by the supplied material.

62% VERIFIED

In an official social-media announcement, Anthropic said an unreleased research version of Claude worked on a mathematics problem connected to the Riemann hypothesis. The company said the system did not solve the hypothesis, but established a 67.2% lower bound for the proportion of Riemann zeta-function zeros lying on the critical line.

The Riemann hypothesis says that every nontrivial zero lies on the line with real part 1/2 and remains unsolved. The provided background sources support the earlier approximate 41.6–41.7% benchmark, but do not independently establish the claimed 67.2% result, its proof, or external expert review. The announcement should therefore be treated as a company research claim rather than a broadly validated mathematical conclusion.

Here are some quick facts about this function. 1. The zeta function converges for complex numbers s with Re(s) > 1. 2. The zeta function can be “analytically continued” so that it is defined on the entire complex plane. 3. The zeta function vanishes at all negative even integers; that is: \(\zeta(s) = 0 \text{ for }s=-2,-4,-6, \dots \) These are called the “trivial zeroes” of the zeta function. The famous (and still unproven) Riemann Hypothesis asserts: All the zeroes of the zeta function (other than the trivial zeroes) lie on the line Re(s)=1/2. The Clay Math Institute has offered a million-dollar prize for anyone who can prove or disprove this conjecture. # Should we try solving it? [...] # Should we try solving it? The general consensus among experts seems to be that RH is simply beyond the reach of what mathematics can prove at the moment. That being said, most open problems seem impossible until they are solved. Fermat’s Last Theorem is a prime example — everyone thought

The Riemann hypothesis, considered one of the greatest unsolved problems in mathematics, asserts that all non-trivial zeros are on the critical line. In 1989, Conrey proved that more than 40% of the non-trivial zeros of the Riemann zeta function are on the critical line. This has since been improved to 41.7%.

The Riemann hypothesis asserts that the nontrivial Riemann zeta function zeros of zeta(s) all have real part ![sigma=R[s]=1/2](/images/equations/RiemannZetaFunction/Inline88.svg), a line called the "critical line." This is now known to be true for the first 250×10^9 roots.

it turns out this is decreasing when the real part of s is bigger than zero and the limit actually is equal to Zer when the real part of s is also bigger than or equal to zero because then basically you have Infinity uh to a positive number which is infinity in the denominator that hopefully appr to zero so you can take a look at these two conditions on your own but this is basically the case when the real part of s is bigger than zero so we end up getting finally is this following thing that that ADA is actually valid for when the real part of s is bigger than zero whereas Zeta is only valid when the of s is bigger than one so now the big question is how do we actually relate these two so if you wrote them out it'll be pretty obvious to see what's going on they're very similar only Ada [...] of x = 1/2 or it intersects the red graph but if we crank K up to 1,000 have to wait a little bit for Desmos to make the change there we go just did it you can actually see the purple has actually
