Geometric Satake

Hot Topics: Recent progress in Langlands Program April 08, 2019 - April 12, 2019

April 08, 2019 (03:30 PM PDT - 04:30 PM PDT)
Speaker(s): Robert Cass (Harvard University)
Location: SLMath: Eisenbud Auditorium



The geometric Satake equivalence is an equivalence between representations of the dual group and equivariant perverse sheaves on the affine Grassmannian. This can be viewed as a local statement happening over a fixed point on a global curve. In this talk I will explain a version of the geometric Satake equivalence over a power of a global curve. I will also describe how this construction is compatible with certain operations over the Beilinson-Drinfeld Grassmannians, such as convolution and fusion.
