In this paper, new generalizations of contra- -continuity by using the class of - -closed sets called ( - , s)-continuity are proudly presented. Characterizations and properties of the class of ( - , s)-continuous functions are investigated and discussed in detail. We obtain various important results in the field of bitopological spaces. Finally, we introduce the two spaces called - -regular spaces and - -normal spaces in bitopological spaces. We obtain several bitopological characterizations of - -regular and - -normal spaces and some preservation theorems for - -regular and - -normal spaces.

- - , - - , - -regular spaces and - -normal spaces.
