Topic of the Workshop

Zeta-functions and multiple-zeta-functions are important objects arising in many mathematical fields: number theory, algebraic geometry, group theory, mathematical physics,
theoretical computer science, graph theory, partial differential equations, fractal geometry, etc. The program will have an emphasis on analytic, diophantine and geometric aspects
of multiple zeta-functions.  The workshop will highlight some recent developments connected with the program.

This Workshop is a part of the  French-Japanese Project "Zeta Functions of Several Variables and  Applications" (Website : 
supported by the French National Center for Scientific Research (CNRS) and the Japan Society for Promotion of Science (JSPS).
This Workshop benefits also from the financial support of the Labex MILYON.

Young researchers  may request financial support to attend the workshop, thanks to our sponsors.
