Abstract

For affine toric varieties X and X ˇ defined by dual cones, we define an equivalence of categories between mixed versions of the equivariant derived category D T b ( X ) and the derived category of sheaves on X ˇ which are locally constant with unipotent monodromy on each orbit. This equivalence satisfies the Koszul duality formalism of Beilinson, Ginzburg, and Soergel.
