We now explain how the representation Green functor Rep and its module category Rep-Mack are present at the very heart of equivariant KK-theory, similarly to the way the Burnside

Given a proper, smooth (formal) scheme over the ring of integers of C p , we prove that if the crystalline cohomology of its special fibre is torsion-free then the p- adic ´

– We construct a “derived” version of Grothendieck’s Quot scheme which is a dg-scheme, i.e., an object RQuot of a certain nonabelian right derived category of schemes.. It has

To prove the perfectness of { , } n , Frey and Rück used a pairing intro- duced by Tate [10], which relates certain cohomology groups of an Abelian variety over a p-adic field, and

(i) For every flat, proper morphism π : X → B (not necessarily of quasi- projective varieties over a field), the subset of B parameterizing points whose geometric fiber is

The (partially) completed singularity category c Sg(A) is defined as the Verdier quotient of the bounded derived category D b (Mod A) of all right A-modules by its full

We prove that if the zeroth cohomology of Γ is finite-dimensional, then the category per Γ/D b Γ is 2-CY and the image of the free dg module Γ is a cluster-tilting object
