On ps-ro Fuzzy Irresolute Functions

摘要

The aim of this paper is to introduce and characterize some new class of function in a fuzzy topological spaces called ps-ro fuzzy irresolute function. The interrelation of this concept with the paralleled existing allied concepts are established. It is shown that the concept of ps-ro fuzzy irresolute function is totally independent of the existing concept of both fuzzy irresolute function and ps-ro fuzzy continuous function. Also it is shown that every ps-ro fuzzy irresolute function is ps-ro fuzzy semicontinuous function but the converse is not true. Further, several characterizations of these functions are established.
