Abstrakt:
Lusztig has constructed enveloping Kac-Moody algebras as constructible functions on some nilpotent part of the cotangent stack of representations of a quiver, and used it to obtain semi-canonical bases for these algebras. Later Kashiwara and Saito constructed the crystal structure of these bases geometrically. I will explain how we can transpose these techniques in the context of curves.
