Certain Types of Weakly Closed Function
weakly closed function
pre-closed set
Gδ set
nd-preserving function
The purpose of this paper is to give the condition under which every weakly closed
function is closed and to give the condition under which the concepts of weaklysemi
closed function and weakly pre-closed function are equivalent. Moreover,
characterizations and properties of weakly semi closed functions and weakly preclosed
function was given.
