On RG-spaces and the regularity degree
Applied General Topology, 2006 We continue the study of a lattice-ordered ring G(X), associated with the ring C(X). Following, X is called RG when G(X) = C(Xδ). An RG-space must have a dense set of very weak P-points.

Multipolar Fuzzy p-Ideals of BCI-Algebras [PDF]
Mathematics, 2019 The notion of (normal) m-polar ( ∈ , ∈ ) -fuzzy p-ideals of BCI-algebras is introduced, and several properties are investigated. Relations between an m-polar ( ∈ , ∈ ) -fuzzy ideal and an m-polar ( ∈ , ∈ ) -fuzzy p-ideal are displayed, and conditions for an m-polar ( ∈ , ∈ ) -fuzzy ideal to be an m-polar ...

n-absorbing I-primary ideals in commutative rings
Tikrit Journal of Pure Science, 2023 We define a new generalization of n-absorbing ideals in commutative rings called n-absorbing I-primary ideals. We investigate some characterizations and properties of such new generalization. If P is an n-absorbing I-primary ideal of R and √IP=I√P, then

The Characteristic of the Minimal Ideals and the Minimal Generalized Ideals in Rings
International Journal of Mathematics and Mathematical Sciences, 2023 In this paper, we prove that the characteristic of a minimal ideal and a minimal generalized ideal, which is meant to be one of minimal left ideal, minimal right ideal, bi-ideal, quasi-ideal, and m,n-ideal in a ring, is either zero or a prime number p ...

Maximal Tukey types, P-ideals and the weak Rudin–Keisler order
Archive for Mathematical Logic, 2023 In this paper, we study some new examples of ideals on $ω$ with maximal Tukey type (that is, maximal among partial orders of size continuum). This discussion segues into an examination of a refinement of the Tukey order -- known as the "weak Rudin-Keisler order" -- and its structure when restricted to these ideals of maximal Tukey type.

A p-Ideal in BCI-Algebras Based on Multipolar Intuitionistic Fuzzy Sets
Mathematics, 2020 In 2020, Kang, Song and Jun introduced the notion of multipolar intuitionistic fuzzy set with finite degree, which is a generalization of intuitionistic fuzzy set, and they applied it to BCK/BCI-algebras.

The Ideal Over Semiring of the Non-Negative Integer
JTAM (Jurnal Teori dan Aplikasi Matematika), 2023 Assumed that (S,+,.) is a semiring. Semiring is a algebra structure as a generalization of a ring. A set I⊆S is called an ideal over semiring S if for any α,β∈I, we have α-β∈I and sα=αs∈I for every s in semiring S.

Invariance of Ideal Limit Points [PDF]
, 2019 Let I be an analytic P-ideal [respectively, a summable ideal] on the positive integers and let (xn) be a sequence taking values in a metric space X. First, it is shown that the set of ideal limit points of (xn) is an Fσ-set [resp., a closet set].

On differentially prime ideals of Noetherian semirings
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2022 The paper is devoted to the investigation of the notion of a differentially prime ideal of a differential commutative semiring (i. e. a semiring equipped with a derivation), and its interrelation with the notions of a quasi-prime ideal and a primary ...

Local inverses of Borel homomorphisms and analytic P‐ideals [PDF]
Abstract and Applied Analysis, 2005 We present a theorem on the existence of local continuous homomorphic inverses of surjective Borel homomorphisms with countable kernels from Borel groups onto Polish groups. We also associate in a canonical way subgroups of ℝ with certain analytic P‐ideals of subsets of ℕ.
