Regular Weakly Contra Open Mappings in Intuitionist Fuzzy Topological Spaces

In this paper we introduce intuitionistic fuzzy contra regular weakly generalized open mappings and intuitionistic fuzzy contra regular weakly generalized closed mappings. We investigate some of their properties.

Regular Weakly Generalized Closed Sets in Intuitionistic Fuzzy Topological Spaces

This paper is devoted to the study of intuitionistic fuzzy topological spaces. In this paper an intuitionistic fuzzy regular weakly generalized closed set and intuitionistic fuzzy regular weakly generalized open set are introduced. Some of its properties are studied. Also we have provided some applications of intuitionistic fuzzy weakly generalized closed set namely intuitionistic fuzzy rwT1/2 ...

ε-weakly Chebyshev subspaces and quotient spaces

Mazur–like topological linear spaces and their products

Topological linear spaces having the property that some sequentially continuous linear maps on them are continuous, are investigated. It is shown that such properties (and close ones, e.g., bornological-like properties) are closed under large products.

On Topological Tensor Products of Functional Fréchet and Df Spaces

A convenient technique for calculating completed topological tensor products of functional Fréchet and DF spaces is developed. The general construction is applied to proving kernel theorems for a wide class of weighted spaces of smooth and entire analytic functions.
