In this paper , we introduce the concept of compactly f-closed set. In this work , we have also shown that where X is a T2-spase,then a subset A of X is compactly f-closed if and only if A is an f-closed set
Moreover , we have studied the concept of compactly f-k-closed set and shown that if the space is T2, then compactly if – closed is equivalent to compactly f-k-closed.
