On Supra b−open Sets and Supra b-continuity on Topological Spaces

O. R. Sayed, Takashi Noiri

Abstract

In this paper, we introduce and investigate a new class of sets and maps between topological spaces called supra

b−open sets and supra b−continuous maps, respectively. Furthermore, we introduce the concepts of supra b-open maps and supra b-closed maps and investigate several properties of them.

Keywords
