A.Pushpalatha et al [11] introduced the concept of *-g-closed set in topological spaces. S. Eswaran and A.Pushpalatha [6] introduced and studied the properties of *-generalized continuous maps and *-gc-irresolute maps in topological spaces. In this paper, we introduce and study a new class of maps called * -generalized open maps and the notion of * -generalized homeomorphism and * -gc-homeomorphism in topological spaces.
