Bernahrd Keller (Paris, FRANCE)

Date: October 25, 2024

Abstract: We will present Miantao Liu's uniform approach to the construction of Goncharov-Shen's basic triangle associated with a split simple Lie group. We will discuss the problem of gluing the corresponding Higgs categories and its solution by Merlin Christ in the case of the group PSL(2, R).
