New Types of Contra b- Continuous Functions

Abstract

This paper continues study continuous functions of contra b-continuous and gives new types of them by introducing new kinds of these function which are (strongly contra b- continuous functions and RC-b- continuous functions) depending on b-open sets, also the study discusses some properties of these functions. Keywords:- ((b-open set, contra b-continuous function, contra-b-irresolute function, strongly contra b-continuous function and RC-b- continuous functions))
