Weak quasi continuity for multifunctions in ideal topological spaces
, 2020The purpose of the present article is to introduce the concepts of almost quasi ?-continuous and weakly quasi ?-continuous multifunctions. Several characterizations of almost quasi ?-continuous and weakly quasi ?continuous multifunctions are investigated.

On quasi-n-ideals of commutative rings
Journal of Algebra and Its Applications, 2023A proper ideal [Formula: see text] of a commutative ring [Formula: see text] is said to be a strongly quasi-primary ideal if, whenever [Formula: see text] with [Formula: see text], then [Formula: see text] or [Formula: see text] (see [S. Koc, U. Tekir and G. Ulucak, On strongly quasi primary ideals, Bull. Korean Math. Soc. 56(3) (2019) 729–743]). This

For a given collection of subsets \(\mathcal A\) of a quasi-ordered set or a poset \(Z\) the author defines the collection \(\mathcal I(\mathcal A)\) of \(\mathcal A\)-ideals of \(Z\). They form a closure system, and this leads to the definition of \(\mathcal A\)-ideal continuity of functions.

On quasi primary ideals and weakly quasi primary ideals
Summary: Let \(R\) be a commutative ring with identity. A proper ideal \(Q\) of \(R\) is called quasi primary (weakly quasi primary) if whenever \(ab\in Q\) (\(0\neq ab\in Q\)) for some \(a, b\in R\), then \(a\in\sqrt{Q}\) or \(b\in\sqrt{Q}\). In this paper, we study quasi primary (weakly quasi primary) ideals which are generalization of prime ideals ...openaire +1 more source

A quasi-ideal Q of a ring A is an additive subgroup of A such that A\(Q\cap QA\subseteq Q\). The intersection of a left ideal and a right ideal is always a quasi-ideal but the converse is not true (a counterexample was constructed by A. H. Clifford [see \textit{O. Steinfeld}, Quasi-ideals in rings and semigroups (1978; Zbl 0403.16001), p. 8]).

Quasi-Ideals and Bi-Ideals in Categories
1997The commutator ideal is used to define quasi-ideals and bi-ideals in categories. These ideals are investigated and examples are given in the category of nearrings.
