• ON WEAKLY SEMI CLOSED SETS IN TOPOLOGICAL SPACES
Abstract
In this research paper, a new class of closed sets called weakly semi closed sets (ws-closed sets) in topological spaces are introduced and studied. A subset A of a topological space (X,t) is called ws-closed set if U contains semi closure of A whenever U contains A and U is w-open set in (X,t). This new class of sets lies between the class of all semi-closed sets and generalised semi-pre regular closed sets in topological spaces. Also some of their properties have been investigated.
