Some New Sets and Topologies in Ideal Topological Spaces

الملخص EN

An ideal topological space is a triplet (X, τ, ℑ), where X is a nonempty set, τ is a topology on X, and ℑ is an ideal of subsets of X.

In this paper, we introduce L∗-perfect, R∗-perfect, and C∗-perfect sets in ideal spaces and study their properties.

We obtained a characterization for compatible ideals via R∗-perfect sets.

Also, we obtain a generalized topology via ideals which is finer than τ using R∗-perfect sets on a finite set.
