Abstract:

Relying on recent advances in the theory of motives we develop a general formalism for derived categories of motives with Q-coefficients on perfect ∞-prestacks. We construct Grothendieck’s six functors for motives over perfect (ind-)schemes perfectly of finite presentation. Following ideas of Soergel–Wendt, this is used to study basic properties of stratified Tate motives on Witt vector partial affine flag varieties. As an application we give a motivic refinement of Zhu’s geometric Satake equivalence for Witt vector affine Grassmannians in this set-up.

Uncontrolled Keywords: Motives, Perfect schemes, Witt vector affine flag variety, Satake equivalence
