g*b-Homeomorphisms and Contra-g*b-continuous Maps in Topological Spaces

Properties of β∗-Homeomorphisms in Topological Spaces

The concept of β∗-homeomorphisms is introduced and investigated by Palanimani [13] earlier. In the present paper we investigate some more properties of β∗-homeomorphisms and also investigate contra β∗-homeomorphisms.

Contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions

The notion of contra continuous functions was introduced and investigated by Dontchev. In this paper, we apply the notion of $beta^{*}$-closed sets in topological space to present and study a new class of functions called contra $beta^{*}$-continuous and almost contra $beta^{*}$-continuous functions as a new generalization of contra continuity.

On G # P - Continuous Maps In Topological Spaces

The aim of this paper is to introduce and study gp-continuous maps. Basic characterizations and several properties concerning them are obtained.Further,gp-irresolute map is also defined. Some of the properties are investigated. 1991 AMS Classification: 54A05, 54D10.

A unified theory of weakly contra-(μ, λ)-continuous functions in generalized topological spaces

We introduce a new notion called weakly contra-(μ, λ)-continuous functions as functions on generalized topological spaces [17]. We obtain some characterizations and several properties of such functions. The functions enable us to formulate a unified theory of several modifications of weak contra-continuity due to Baker [9].
