On Pairwise #pi-g-s - Closed maps in Bitopological Spaces

Abstract

In this paper we introduce the class of closed sets namely (1, 2)* - generalized^{(1, 2)*- πgb} semi  -closed sets (briefly(1,2)*- #πgs closed sets) and discuss some of their properties in bitopological spaces.Further, we define and study a new class of generalized maps called (1,2)* generalized^{(1, 2)*- πgb} semi-closed maps(briefly(1,2)*-#πgs- closed maps). Also, we give some characterizations and applications of  it.
