Note on strongly quasi-primary ideals
Abstract
Let R be a commutative ring with 1≠0. A proper ideal I of R is said to be a strongly quasi-primary ideal if, whenever a,b∈R with ab∈I, then either a2∈I or b∈√I. In this paper, we characterize Noetherian and reduced rings over which every (respectively, nonzero) proper ideal is strongly quasi-primary. We also characterize ring over which every strongly quasi primary ideal of R is prime. Many examples are given to illustrate the obtained results.
