Geometric Satake, Springer correspondence, and small representations II

Pramod N. Achar, Anthony Henderson, Simon Riche

For a split reductive group scheme $G$ over a commutative ring $k$ with Weyl group $W$ , there is an important functor $R e p (G, k) \to R e p (W, k)$ defined by taking the zero weight spac…
