• ON FUZZY SEMI-PRE-BOUNDARY
Abstract
In this paper we introduce the concept of fuzzyC -semi-pre-boundary by using the arbitrary complement functionC and by using fuzzyC -semi-pre closure of a fuzzy topological space where C :[0, 1]® [0, 1] is a function. Let l be a fuzzy subset of a fuzzy topological space X and let C be a complement function. Then the fuzzy C –semi-pre- boundary of l is defined as SPBdC l = SPClC l Ù SPClC (C l), where SPClC l is the fuzzy C -semi-pre-closure of l and C l(x) = C (l (x)), 0 £ x £ 1. In this paper we discuss the basic properties of fuzzy C -semi-pre-boundary.
