Abstract: |
The group scheme of regular centralizers is an interesting algebraic symplectic manifold associated to a complex reductive group. Quantizing, one obtains a category with a commutative multiplication operation. I will explain how objects of this category define central symmetries of categories equipped with an action of G. The construction uses the derived form of geometric Satake due to Bezrukavnokov and Finkelberg. This is joint work with David Ben-Zvi. |
