French-Japanese Conference on Arithmetic Geometry in Honor of Takeshi Saito and Takeshi Tsuji

French-Japanese Conference on Arithmetic Geometry in Honor of Takeshi Saito and Takeshi Tsuji        May 31 – June 4, 2027 at IHES – Marilyn and James Simons Conference Center    How to get to IHES

This conference, which is part of a long-standing tradition of French-Japanese collaboration in arithmetic geometry, will honor two leading figures of this partnership: Professor Takeshi Saito, on the occasion of his retirement, and Professor Takeshi Tsuji, on the occasion of his 60th birthday.
The main topics of the conference will include:

p-adic Hodge theory, including the p-adic Simpson correspondence, geometric Sen theory, p-adic Galois representations and (φ,Γ)-modules, prismatic cohomology, and their applications;

Ramification theory, including singular support and characteristic cycles of l-adic étale sheaves (in equal and mixed characteristic), compatibility with proper higher direct images, Swan conductors, and epsilon-factors;

Geometric Langlands theory, l-adic, p-adic, and for modules with integrable connections, in characteristic p and in characteristic 0.
