Separating versus strictly separating vectors

Abstract

Let S S be a linear manifold of Banach space operators which is closed in the strong operator topology. Existence of a disjoint pair of separating vectors does not guarantee reflexivity of S S , but S S must be reflexive if one of these vectors is strictly separating. S S must also be reflexive if all non–zero linear combinations of some independent pair of vectors strictly separate S S .
