Amitsur cohomology of algebraic number rings

David Earl Dobbs

Vol. 39 (1971), No. 3, 631–635
Abstract

A bound is given for the order of the Amitsur cohomology group Hi(S∕R,U) corresponding to an extension R S of rings of algebraic integers. The effect of inflation on the ChaseRosenberg exact sequence involving Amitsur cohomology and split Brauer groups is also studied.
