In [4], Dontchev introduced and investigated a new notion of continuity called contra-continuity. Recently, Jafari and Noiri ([8], [9], [10]) introduced new generalization of contra-continuity called contra-super-continuity, contra-(…)-continuity and contra-precontinuity. It is the objective of this paper to introduce and study a new class of contra-continuous functions via (…)-closed sets.
