LINEAR KOSZUL DUALITY

By Ivan Mirković and Simon Riche

Abstract

In this paper we construct, for F1 and F2 subbundles of a vector bundle E, a “Koszul duality” equivalence between derived categories of Gm-equivariant coherent (dg-)sheaves on the R derived intersection F1∩EF2, and the corresponding derived intersection F ⊥R 1 ∩E∗F ⊥ 2. We also propose applications to Hecke algebras
