# Periods in Number Theory, Algebraic Geometry and Physics

Trimester Program

January 3 - April 20, 2018

Organizers: Spencer Bloch (Chicago), Herbert Gangl (Durham), Vasily Golyshev (Moscow), Fernando Rodriguez Villegas (Trieste), Don Zagier (Bonn)

The word "period" is used to designate any number represented by the integral of an algebraic differential form over a cycle in an algebraic variety over $\mathbb{Q}$ (or $\overline{\mathbb{Q}}$). These include many numbers of interest in number theory and mathematical physics (multiple zeta values, Mahler measures, superstring amplitudes, ...), and also have deep connections with special values of motivic L-functions.

The trimester will be divided into five "activities", each concentrating on one topic and including one or several introductory courses, and also three one-week workshops featuring lectures on current work:

Those planning to participate include:
Yves André, Joseph Ayoub, Alexander Beilinson, David Broadhurst, Francis Brown, José Burgos Gil, Henri Cohen, Christopher Deninger, Charles Doran, Hélène Esnault, Javier Fresán, Alexander Goncharov, Benedict Gross, Richard Hain, Annette Huber-Klawitter, Matt Kerr, Dirk Kreimer, Marc Levine, Steve Lichtenbaum, Madhav Nori, Dinakar Ramakrishnan, David Roberts, Jan Stienstra, Tomohide Terasoma, Pierre Vanhove, Wadim Zudilin

The trimester program is supported by the Max Planck Institute for Mathematics. We are grateful for this support.
