Abstract
In this article, we introduce several types of generalized regular closed sets in topological spaces, using the concepts of v-sets, the class of generalizations contains the sets; regular v-sets, generalized regular v-sets, generalized star v-set and generalized star regular ᴠ-set. We illustrate the inter-relations between these sets, then we study the characterization of this class, which relative to unions, intersections and subspaces, finally we investigate their behavior in regular spaces and extremely disconnected spaces.
