The ideal generated by σ-nowhere dense sets

open access: yesApplied General Topology, 2006
In this paper, we consider the ideal Iσ generated by all σ-nowhere dense sets in a topological space. Properties of this ideal and its relations with the Volterra property are explored.

Compatible elements in partly ordered groups [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Some conditions equivalent to a strong quasi-divisor property (SQDP) for a partly ordered group G are derived. It is proved that if G is defined by a family of t-valuations of finite character, then G admits an SQDP if and only if it admits a quasi ...

A new local function and a new compatibility type in ideal topological spaces

open access: yesAIMS Mathematics, 2023
<abstract><p>In this study, a $ \zeta^*_\Gamma $-local function is defined and its properties are examined. This newly defined local function is compared with the well-known local function and the local closure function according to the relation of being a subset.

Introduction to generalized topological spaces

open access: yesApplied General Topology, 2011
We introduce the notion of generalized topological space (gt-space). Generalized topology of gt-space has the structure of frame and is closed under arbitrary unions and finite intersections modulo small subsets. The family of small subsets of a gt-space

Ideal Magnetic Dipole Scattering [PDF]

open access: yes, 2017
We introduce the concept of tunable ideal magnetic dipole scattering, where a nonmagnetic nanoparticle scatters light as a pure magnetic dipole. High refractive index subwavelength nanoparticles usually support both electric and magnetic dipole responses.

R-Compatible Ideals of topological spaces

open access: yesWasit Journal for Pure sciences, 2023
Abstract. This paper's goal is to present the idea of regular-compatibility of ideals by replaced the open set is Regular-open set  and with respect to topology, which is abbreviated as (τ ∼ R I ),  Using a brand-new local function termed the regular-local function A(*R) (I, T), it is also possible to examine the connection between this idea and the ...

*-Topological properties

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
An ideal on a set X is a nonempty collection of subsets of X closed under the operations of subset (heredity) and finite unions (additivity). Given a topological space (X,τ) an ideal ℐ on X and A⊆X, ψ(A) is defined as ⋃{U∈τ:U−A∈ℐ}. A topology, denoted τ*,
