• ON NANO (1, 2)* GENERALIZED-REGULAR CLOSED SETS IN NANO BITOPOLOGICAL SPACES

T he purpose of this paper is to define and study a new class of set called Nano (1, 2)* generalized-regular closed sets in nano bitopological spaces. Basic properties of nano (1, 2)* generalized regular closed sets are analyzed. The new notion of nano (1, 2)* generalized-regular closure and their relation with already existing well known sets are also investigated.
