18 June, 2012, 2PM, room 119, Michael Atiyah Building.

A famous mathematician, Yuri Matiyasevich, will visit us and give a talk.

Yurii Matiyasevich is best known for his negative solution of Hilbert's tenth problem: He proved that there is no algorithm which can solve all Diophantine equations. More information about his achievements and awards you can find in http://en.wikipedia.org/wiki/Yuri_Matiyasevich .

Yuri Matiyasevich will talk about zeros of Riemann's zeta function, the conjecture which belongs to the so-called "Millennium problems". These are seven problems in mathematics that were selected by the Clay Mathematics Institute in 2000 as the most important unsolved mathematical problems. As of June 2012, six of the problems remain unsolved. A correct solution to any of the problems results in a US$1,000,000 prize (sometimes called a Millennium Prize)

The talk will be interesting for both pure and applied mathematicians; it will also be understandable for PhD students and include enough introductory and review material.

New conjectures about zeros of Riemann's zeta function

 

Abstract: the speaker described a surprising method for (approximate) calculation of the zeros of Riemann's zeta function using terms of the divergent Dirichlet series. In the talk this method will be presented together with some heuristic hints explaining why the divergence of the series doesn't spoil its use. Several conjectures about the zeros of Riemann's zeta function will be stated including supposed new relationship between them and the prime numbers.
