A Bitopological (1,2)* Semi-generalised Continuous Maps

Abstract. We introduce a new type of generalized sets called (1, 2)* semi- generalized closed sets and a new class of generalized functions called (1, 2)* semi-generalized continuous maps. We obtain several characterizations of this class and study its bitopological properties and investigate the relationships with other new functions like (1, 2)* g-continuous maps and (1, 2)* gc-irresolute maps.
