Summer Workshop on Character Sheaves on Loop Groups

Overview

Lusztig's theory of character sheaves for reductive groups provides  powerful geometric tools for harmonic analysis over finite fields. In recent years, there has been impressive development in the generalization of character sheaves theory to loop groups.  These advances uncover deep geometric structures underlying representation and harmonic analysis over p-adic fields, leading to new perspectives on the local aspect of the arithmetic and geometric Langlands program. We are hosting a workshop with lectures covering a broad range of topics connected with character sheaves on loop groups, its applications, and related future directions.
