A new generalızatıon of (m, n)-closed ıdeals

Abstract

Let R be a commutative ring with identity. For positive integers m and n, Anderson and Badawi (Journal of Algebra and Its Applications 16(1):1750013 (21 pp), 2017) defined an ideal I of a ring R to be an (m,n)-closed if whenever xm∈ I , then xn∈ I . In this paper we define and study a new generalization of the class of (m,n)-closed ideals which is the class of quasi (m,n)-closed ideals. A proper ideal I is called quasi (m,n)-closed in R if for x∈ R , xm∈ I implies either xn∈ I or xm-n∈ I . That is, I is quasi (m,n)-closed in R if and only if I is either (m, n)-closed or (m, m- n)-closed in R. We justify several properties and characterizations of quasi (m,n)-closed ideals with many supporting examples. Furthermore, we investigate quasi (m,n)-closed ideals under various contexts of constructions such as direct products, localizations and homomorphic images. Finally, we discuss the behavior of this class of ideals in idealization rings. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
