Abstract We define a unital algebra A over a field to be nearly simple if A contains a unique non-trivial ideal IA such that If A and B are two nearly simple algebras over , we consider the ideal structure of their tensor product The obvious non-trivial ideals of are: The purpose of this article is to characterize when are all non-trivial ideals of of the above form.
