Wedderburn decomposition of commutative semisimple group algebras using the Combinatorial Nullstellensatz
Abstract
In this paper, we present the simple components of the Wedderburn decomposition of semisimple commutative group algebras over finite abelian groups, which we investigate from a geometric point of view. We also present the Wedderburn decomposition of semisimple commutative group algebras over finite fields.
