On supra e*-open sets and supra e*-continuous functions

Abstract

In the present study, we introduced a novel type of generalized supra open sets called supra $e^*$-open sets via supra $\delta$-closure operator which we define. Through this new concept, we defined and studied supra $e^*$-continuous functions, supra $e^*$-open functions and supra $e^*$-closed functions. Also, we investigated relationships between supra $e^*$-continuous functions and different generalized types of supra continuity.
