The concept of b-open sets was introduced by Andrijevic. The aim of this paper is to introduce and characterize weakly b-irresolute functions by using b-open sets. 2000 Mathematics Subject Classification: 54C05.

In this paper we introduce and study the concepts of intuitionistic fuzzy g*continuous mappings and intuitionistic fuzzy g*-irresolute mappings and some of their basic properties are discussed.

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.

In this paper, we introduce the concepts of fuzzy pairwise (r, s)-irresolute, fuzzy pairwise (r, s)-presemiopen and fuzzy pairwise (r, s)-presemiclosed mappings in smooth bitopological spaces and then we investigate some of their characteristic properties.

Shabir and Naz in [25] introduced the notion of soft topological spaces. They defined basic notions of soft topological spaces such as open soft sets, closed soft sets, soft subspaces, soft closure, soft nbd of a soft point, soft separation axioms, soft regular spaces, soft normal spaces and they established their several properties. Min in [19] investigated some properties of such soft separat...

Aim of this present paper is, we introduce and investigate neutrosophic Z-continuous maps which is a new kind continuous in topological spaces. Also discussed about some properties characterization Z-irresolute maps.

In this paper we have introduced a new class of closed in topological spaces called g**-closed sets and study some its properties . Further introduce the concept g**-continuous functions , g**-irresolute As an application two news paces namely T **-space, **T - space .Further, g**-continuous, mappings are also investigated
