Contra-continuous functions defined through Λ<inf>I</inf>-closed sets

Abstract:

We introduce some variants of contra-continuity in terms of ΛI-closed sets, namely contra-ΛIcontinuous, contra quasi-ΛI-continuous and contra ΛI-irresolute functions. The relationships between these functions are investigated and their respective characterizations are established. Moreover, we study their behavior of several topological notions under the direct and inverse images of these functions.
