(Equivariant) Cohomology of the affine Grassmannian and
Ginzburg’s picture
This is the second talk in a series of three talks on the
derived Satake. I will give an overview of an article by Ginzburg
which laid the foundational ideas for this...
This is the first talk in a series of three talks towards
understanding Bezrukavnikov-Finkelberg's derived geometric Satake
equivalence. In this talk, we recall the geometry of equal
characteristic affine Grassmannians and some of the ingredients
of...
We will discuss p-local representation theory and conjectures of
Broue and Alperin, the latter been inspired by finite groups of Lie
type in characteristic p. The issue is the extent to which the
category of representations can be reconstructed from...
In this second talk about Broué’s Abelian Defect Group Conjecture,
we will explain its geometric version in the case of finite groups
of Lie type: the equivalence should be induced by the cohomology
complex of Deligne-Lusztig varieties. This was...
This talk will form part of a series of three talks focusing on
Broué’s Abelian Defect Group Conjecture, which concerns the modular
representation theory of finite groups. We will pay particular
attention here to the ‘geometric’ form of the...
