Abstract

As an extension of an author's previous paper, we prove the Gersten-type conjecture for the mod pp \'{e}tale motivic cohomology over a local ring of mixed characteristic (0,p)(0, p). We also prove the P1\mathbb{P}^{1}-homotopy invariance for the generalized Brauer group which is a genelization of a result due to Saltman in mixed characteristic cases.
