Alpha weakly semi closed sets in topological spaces

General topology plays a significant role in space time geometry as well as in different branches of mathematics. The notations of sets and functions in topological spaces are highly developed and used extensively in many practical and engineering problems.Closed sets are fundamental objects in a topological spaces. Example one can define the topology on a set by using either axioms for the closed sets or the Kurtowski closure axioms. Closure and interior operators are basic concepts for the study and investigations in general topological spaces. Now these two operators are widely used in computer applications and approximations,for example rough set theory where the topological structure is used as a knowledge base for extracting knowledge from available information.In 1970, Levine introduced generalized closed (briefly g-closed) sets in topology. Researches in topology studied several versions of generalized closed sets.My objective is to investigate ¿Alpha Weakly Semi Closed (briefly ¿ws-closed) sets in topological spaces¿.
