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

open access: yesCommentationes 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).

P-ideal dichotomy and a strong form of the Suslin Hypothesis

Fundamenta Mathematicae, 2020
Summary: We introduce a forcing notion which forces the P-ideal dichotomy, while every almost Suslin tree from the ground model remains non-special. Thus, while the P-ideal dichotomy implies the Suslin Hypothesis, or equivalently that every Aronszajn tree has an uncountable antichain, it does not imply that every Aronszajn tree has a stationary ...

L-spaces and the P-ideal dichotomy

Acta Mathematica Hungarica, 2009
\textit{S. Todorčević} [Partition problems in topology. Contemporary Mathematics, 84. Providence, RI: American Mathematical Society (AMS) (1989; Zbl 0659.54001)] proved that his principle (\(\mathcal K\)) implies that there are no strong \(L\)-spaces of countable tightness; more precisely, \((*)\): a regular space with all finite powers Lindelöf ...

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.
