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