Laboratory Colloquium: Don Zagier (MPI for Mathematics, Bonn) и Alessio Corti (Imperial College London)

Sep 29 at  room 427

17:00   Don Zagier (MPI for Mathematics, Bonn), Poor man's adeles and multiple zeta values.

Abstract: The «poor man's adeles» of the title is the informal name of the ring whose elements are «numbers» having a well-defined value modulo almost every prime number. It turns out that examples of elements of this ring show up in many places in mathematics. In the lecture I will describeseveral examples of this, most notably a finite-field version of the well-known multiple zeta values invented by Euler and much studied in recent years (this part is joint work with Masanobu Kaneko), but also examples coming from areas as different as quantum invariants of homology 3-spheres and transition matrices between different bases of the space of solutions of a linear differential equation with regular singularities.

18:30   Alessio Corti (Imperial College London) Fano varieties and mirror symmetry

Abstract: After discussing the words in the title, I will sketch a project to classify Fano varieties inspired by mirror symmetry.
