A generalization of the Picard-Brauer exact sequence

Algebraic Geometry 2009-03-03 v1 Number Theory

Abstract

We extend an argument of S.Lichtenbaum involving codimension one cycles to higher codimensions and obtain a generalization of the well-known Picard-Brauer exact sequence for a smooth variety X. The resulting exact sequence connects the codimension n Chow group of X with a certain "Brauer-like" group.
