Failure of flat descent of model structures on module categories

Algebraic Topology 2015-01-07 v1 Category Theory

Abstract

We prove that the collection of model structures on (quasicoherent) module categories does not obey flat descent. In particular, it fails to be a separated presheaf, in the fppf topology, on Artin stacks.
