Abstract

In this paper, a new class of sets called regular w-closed (briefly rw-closed) sets in topological spaces is introduced and studied. A subset $A$ of a topological space $(X,\tau )$ is called rw-closed if $U$ contains closure of $A$ whenever $U$ contains $A$ and $U$ is regular semiopen in $(X,\tau )$. This new class of sets lies between the class of all w-closed sets and the class of all regular g-closed sets. Some of their properties are investigated.
