Abstract
In this paper, we introduce and investigate a new class of sets called (1, 2)∗-ï°gï¨-closed and some new functions called (1, 2)∗-ï°gï¨-continuous, almost (1, 2)∗-ï°gï¨-continuous functions in bitopological spaces. Moreover we obtain the relationships among some existing closed sets like (1, 2)∗-ï°gï¨-closed, (1, 2)∗-semi-closed, (1, 2)∗-ï¡-closed and (1, 2)∗-ï¨-closed sets and their generalizations. Also we study some basic properties of (1, 2)∗-ï°gï¨-closed sets. Further, we introduce (1, 2)∗-ï°gï¨-neighbourhood and discuss some properties of (1, 2)∗-ï°gï¨-neighbourhood.
Keywords: (1, 2)*-ï¨-open, (1, 2)*-gï¨-closed, (1, 2)*-ï°gï¨-closed sets; (1, 2)∗-ï°gï¨-continuous, almost (1, 2)∗-ï°gï¨-continuous functions.
