On 2-absorbing quasi-primary ideals in commutative rings. (English) Zbl 1338.13007

Summary: Let \(R\) be a commutative ring with nonzero identity. In this article, we introduce the notion of 2-absorbing quasi-primary ideal which is a generalization of quasi-primary ideal. We define a proper ideal \(I\) of \(R\) to be 2-absorbing quasi primary if \(\sqrt{I}\) is a 2-absorbing ideal of \(R\). A number of results concerning 2-absorbing quasi-primary ideals and examples of 2-absorbing quasi-primary ideals are given.
