Abstract
In this paper, a new class of sets and maps between topological spaces called supra pre-open sets and supra pre-continuous maps, respectively are introduced and studied. Furthermore, the concepts of supra pre-open maps and supra pre-closed maps in terms of supra pre-open sets and supra pre-closed sets, respectively, are introduced and several properties of them are investigated.
