On characterizations of a some classes of Schauder frames in Banach spaces
Abstract
In this paper, we prove the following results. There exists a Banach space without basis which has a Schauder frame. There exists an universal Banach space (resp. ) with a basis (resp. an unconditional basis) such that, a Banach has a Schauder frame (resp. an unconditional Schauder frame ) if and only if is isomorphic to a complemented subspace of (resp. ). For a weakly sequentially complete Banach space, a Schauder frame is unconditional if and only if it is besselian. A separable Banach space has a Schauder frame if and only if it has the bounded approximation property. Consequenty, The Banach space of all bounded linear operators on a Hilbert space has no Schauder frame. Also, if and are Banach spaces with Schauder frames then, the Banach space (the projective tensor product of and ) has a Schauder frame. From the FaberSchauder system we construct a Schauder frame for the Banach space (the Banach space of continuous functions on the closed interval ) which is not a Schauder basis of . Finally, we give a positive answer to some open problems related to the Schauder bases (In the Schauder frames setting).
