Zusammenfassung
The goal of this small note is to give a more concise proof of a result due to Berthelot, Esnault, and Rulling in [4]. 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 structure sheaf of the generic fibre of X with the vanishing of the Witt vector cohomology of its special fibre.

We use as a critical ingredient results and constructions by Beilinson [2] and Nekovar-Niziol [14] related to the h-topos over a p-adic field. (c) 2019 Elsevier Inc. All rights reserved.
