Abstract :

First, we obtain some results on compactly invariant subspaces in normed spaces. Then we introduce the notion of compactly coinvariant pair. Also, a sufficient condition for a normed space $X$ has a compactly coinvariant pair, is given.

Keywords :

Compactly invariant subspace, Compactly coinvariant subspace, Reflexive space.
