Abstract

The aim of the present paper is devoted to discuss some more properties of γ-irresolute mappings and contra-γ-irresolute mappings. Also, we introduce and study two new weak homeomorphisms such as contra-γr-homeomorphisms and contra- γ-homeomorphisms. Further, we investigate some groups related to the mappings above and some examples of them on digital lines.
