Abstract

In 1927 P\'olya proved that the Riemann Hypothesis is equivalent to the hyperbolicity of Jensen polynomials for the Riemann zeta function ζ(s)\zeta(s) at its point of symmetry. This hyperbolicity has been proved for degrees d3d\leq 3. We obtain an asymptotic formula for the central derivatives ζ(2n)(1/2)\zeta^{(2n)}(1/2) that is accurate to all orders, which allows us to prove the hyperbolicity of a density 11 subset of the Jensen polynomials of each degree. Moreover, we establish hyperbolicity for all d8d\leq 8. These results follow from a general theorem which models such polynomials by Hermite polynomials. In the case of the Riemann zeta function, this proves the GUE random matrix model prediction in derivative aspect. The general theorem also allows us to prove a conjecture of Chen, Jia, and Wang on the partition function.
