In this work, we study and introduce new type of open sets is called -open. We characterize these sets and investigate some of their mainly properties. Further, we present various functions are associated with -open, called -open, M -open, and weakly -open. We also discuss many characterizations, properties, and relations are discussed. Finally, we study  -separation axioms by using -set
