Wedderburn Decomposition and Idempotents of some finite metacyclic group algebras
Abstract
In this article, we show explicitly the Wedderburn decomposition of the metacyclic group algebra FqG, where G has a cyclic subgroup of index 2 and (|G|,q)=1. We also construct the complete set of central and left idempotents of these group algebras.
