Semi-Open Sets And Pre Open Sets In Tri Topological Space

Source abstract

The main aim of this paper is to introduce two new types of open sets, namely tri semi open sets and tri pre open sets in tri topological spaces along with their several properties and characterization. As application to tri open sets, tri semi open sets and tri pre open set, the authors introduce tri continuous, tri semi continuous, and tri pre continuous functions to obtain some of their basic properties.
