Abstract:

I'll give a geometric description of the category of representations of a quantum group at a root of unity. This will be in terms of the Springer resolution in characteristic zero. A similar description exists for the category of representations of a Lie algebra in positive characteristic. I'll explain how from this one can deduce that the modular and root of unity representation theories "look alike". This is joint work with Erik Backelin.
