内容	In this talk I would like to explain a shorter and more conceptual proof of a result due to Berthelot, Esnault, and Rülling. For a regular, proper, and flat scheme X over a discrete valuation ring of mixed characteristic (0,p),it relates the vanishing of the cohomology of the generic fibre of X with the vanishing of the Witt vector cohomology ofits special fibre. We use as a critical ingredient results and constructions by Beilinson and Nekovár-Nizioł related to the h-topos over a p-adic field.
