Short course on Nonabelian Hodge theory

Short course on Nonabelian Hodge theory

by Prof. Florent Schaffhauser

(Universidad de Los Andes (Bogotá); Max Planck Institute (Bonn); University of Strasbourg)

Waseda University
July 2021
(via real-time Zoom lectures*)

Associate Professor Florent SCHAFFHAUSER

The course will be an introduction to nonabelian Hodge theory over compact Riemann surfaces, with a view towards the topology of character varieties. A significant part of the course will be devoted to the ideas and techniques used in Simpson’s famous proof of the nonabelian Hodge correspondence. The central notion of the course will be that of a Higgs bundle, which was introduced by Hitchin, and can be seen as a degenerate version of a holomorphic bundle with connection.

Each lecture will include ample time for discussion and questions. There will also be discussion sessions following the lectures, in which students can present their own research and receive advice from the lecturer.

Graduate students and researchers in mathematics, physics, and engineering are welcome (see below for registration information).
