In this paper the properties of space of the G-permutation degree, like: weight, uniform connectedness and index boundedness are studied. It is proved that: (1) If (X, U) is a uniform space, then the mapping π s n, G : (X n , U n ) → (SP n GX, SP

A. V. Arhangelskii introduced the dimension Dind and properties of this dimension have been studied for various classes of topological spaces. In this paper, we study this dimension for finite T 0-spaces. Especially, we prove that in the realm of fin

In this paper, we do further investigations on the statistical inner and outer limits of sequences of closed sets in metric spaces, which were introduced by Nuray, Rhoades, and Talo, Sever, Başar, and generalize the conventional Painleve-Kuratowski

The notion of sequential convergence in fuzzy partially ordered sets, under the name oF-convergence, is well known. Our aim in this paper is to introduce and study a notion of net convergence, with respect to the fuzzy order relation, named o-converg

The notion of rU-space is given and investigated. A space X is said to be a rU-space if X is a Hausdorff space and for every x ∈ X and every open neighbourhood V of x there exists an open neighbourhood U of x such that U ⊆ Cl(V) and Bd(U) ⊆ V.

In this paper we prove that for a fixed integer or an ordinal $$\alpha $$ and a fixed infinite cardinal $$\tau $$ the class of all regular frames of weight less than or equal to $$\tau $$ with small inductive dimension less than or equal to $$\alpha
