A generalization of Serre's condition (F) with applications to the finiteness of unramified cohomology

Abstract

In this paper, we introduce a condition ${(\mathrm{F}}_m^{\prime })$ on a field $K$, for a positive integer $m$, that generalizes Serre's condition (F) and which still implies the finiteness of the Galois cohomology of finite Galois modules annihilated by $m$ and algebraic $K$-tori that split over an extension of degree dividing $m$, as well as certain groups of étale and unramified cohomology. Various examples of fields satisfying ${(\mathrm{F}}_m^{\prime })$, including those that do not satisfy (F), are given.
