The Steinberg variety and the equivariant coherent sheaves on it play a very important role in Geometric Representation Theory. In this talk we will discuss various t-structures on the equivariant derived category of the Steinberg of importance for Representation Theory in zero and positive characteristics.
This talk is based on this arXiv paper and work in progress.
This video was produced by the International Centre for Mathematical Sciences, as part of the workshop Geometric Representation Theory and W-algebras.
