p-Ideals in p-Regular Semirings

Southeast Asian Bulletin of Mathematics, 2003
Let \((S,+,\cdot)\) be an additively commutative semiring. If \((S,+)\) is an inverse semigroup, \(S\) is called inversive. The semiring \(S\) is \(p\)-regular if for each \(a\in S\) there is some \(b\in S\) such that \(na+aba=(n+1)a\) for some natural number \(n\). If \(S\) is inversive, this condition reduces to \(a+aba = 2a\). An ideal \(I\) of \(S\)

p-ideals of BCI-algebras based on neutrosophic N -structures

Journal of Intelligent & Fuzzy Systems, 2021
In this paper, neutrosophic N -structures are applied to p-ideals of BCI-algebras. In fact, we introduce the notion of neutrosophic N -p-ideal in BCI-algebras, and investigate several properties. Further, we present characterizations of neutrosophic N -p-ideal.

Extending the ideal of nowhere dense subsets of rationals to a P-ideal [PDF]

Commentationes Mathematicae Universitatis Carolinae, 2013
summary:We show that the ideal of nowhere dense subsets of rationals cannot be extended to an analytic P-ideal, $F_\sigma$ ideal nor maximal P-ideal. We also consider a problem of extendability to a non-meager P-ideals (in particular, to maximal P-ideals)

Epimorphic Image of P-Ideals of P-Algebras

SUST Journal of Science and Technology (SUST JST), 2020
In this paper, we study p-ideals of a p-algebra. We prove that epimorphic image of a p-ideal is a p-ideal. Our main result is that the lattice of p-ideals of a p-algebra L is isomorphic to the lattice of ideals of the Boolean algebra formed by the closed elements of L.

P-ideal dichotomy and Tukey order

Fundamenta Mathematicae
Summary: The P-ideal dichotomy is a simple and natural principle about P-ideals of countable subsets of some index set. It has proven to be particularly useful in problems involving sequential convergence in topological spaces. This is explored further here with the aim to relate it to the theory of Tukey reductions of directed sets.

Soft set theory applied to p-ideals of BCI-algebras related to fuzzy points

Neural Computing and Applications, 2010
The notions of $$(\overline{\in}, \overline{\in} \vee \overline{\hbox{q}})$$ -fuzzy p-ideals and fuzzy p-ideals with thresholds related to soft set theory are discussed. Relations between $$(\overline{\in}, \overline{\in} \vee \overline{\hbox{q}})$$ -fuzzy ideals and $$(\overline{\in}, \overline{\in} \vee \overline{\hbox{q}})$$ -fuzzy p-ideals are ...

On the Lebesgue decomposition of a function relative to a \(p\)-ideal of an orthomodular lattice

1991
Summary: We establish a decomposition theorem in which a finitely additive group- valued function defined on an orthomodular lattice is decomposed with respect to a \(p\)-ideal.

Connections between matrix summability ideals and nonpathological analytic P-ideals

Fundamenta Mathematicae
The paper focuses on the connection between two classes of analytic P-ideals: nonpathological ideals (those generated by nonpathological submeasures) and matrix summability ideals (those generated by regular infinite matrices). The first main result is that an analytic P-ideal is the intersection of some matrix summability ideals if and only if it is ...
