Moreover, the relationships of other related classes of sets are investigated. Also, a new decomposition of continuous functions is obtained by using delta - beta - I - continuous and S* - continuous functions.eninfo:eu-repo/semantics/openAccessideal topological spacesemi*-I-open setdelta alpha-I-open setS*-continuousArticle162433445WOS:000298632700011Q4
