On πgI-Closed Sets in Ideal Topological Spaces
نویسندگان
چکیده
In this paper, we define and investigate the notions of πgI-closed sets and πgI-open sets in ideal topological spaces. Then, we define ∨π-sets and ∧π-sets and discuss the relation between them. Also, we give characterizations of πgI-closed sets and πgs-closed sets. A separation axiom stronger than πTI -space is defined and various characterizations are given.

متن کاملOn $beta-$topological vector spaces
We introduce and study a new class of spaces, namely $beta-$topological vector spaces via $beta-$open sets. The relationships among these spaces with some existing spaces are investigated. In addition, some important and useful characterizations of $beta-$topological vector spaces are provided.
