Abstract

We define and characterize a fuzzy pairwise strongly pre-continuous mappings on a fuzzy bitopological space. We investigate some of their properties. We establish some equivalent conditions of fuzzy pairwise strongly precontinuous mappings on a fuzzy bitopological space.

INTRODUCTION

In 1981, K.K. Azad [4] introduced the concept of semi-open sets in fuzzy topology. A.S. Bin Shahana [1] has defined the concept of fuzzy pre-open sets in fuzzy topological spaces.

In 1989, A. Kandil [5] introduced the notation of fuzzy bitopological space. Further in 1996, S.S. Thakur and R. Malviya [9] defined fuzzy semi-open and fuzzy semi-continuous in fuzzy bitopological space. Sampath kumar [10] defined a (τi, τj)-fuzzy pre-open set and characterized a fuzzy pairwise precontinuous mappings on a fuzzy bitopological space. Further M. Shrivastava, J.K.m maitra And M. Shukla [7] in 2006 defined fuzzy strongly pre-continuous mapping in fuzzy topological space

In this article we have established equivalent conditions for a mapping to be fuzzy pairwise strongly pre-continuous mapping in fuzzy bitopological space. Further we have studied some properties of fuzzy pairwise pre-continuous mapping.

Concluding remark:

1. We have introduced and studied new kind of map fuzzy pairwise Strongly pr-econtinuos maps on fuzzy bitopological spaces.

2. We defined the relation between fuzzy pairwise pre continuous and fuzzy pairwise strongly continuous map. We investigated some of their properties.

3. We proved that the fuzzy pairwise storgly pre-continuous map is stronger form of fuzzy paqairwise pre-continuous map by use of example.

4. We have established some significant properties of fuzzy pairwise strogly pre-continuous maps.

5. We introduce and study new kind of fuzzy pairwise strongly pre-closed and investigate of their properties.
