Decomposition of Separation Axioms: On ¿-Open Sets - Softcover

Inhaltsangabe

The goal of this a book is to recall some types of weak open sets, prove some of its properties and use them to define new kinds of separation axioms. Let us state below some of our important main theorems Let (X,¿) and (Y,¿) be two topological spaces satisfy the ¿-condition then the map f:(X,¿)¿(Y,¿) is continuous if and only if it is ¿-continuous. ( This result is not true without ¿-condition ), also Let (X,¿) and (Y,¿) be two topological spaces satisfy the ¿-B_¿-condition then the map f:(X,¿)¿(Y,¿) is continuous if and only if it is ¿-¿-continuous.
