Frames containing a Riesz basis and preservation of this property under perturbation
Peter G. Casazza, Ole Christensen
Aldroubi has shown how one can construct any frame $\gtu$ starting with one frame $\ftu $,using a bounded operator on . We study the overcompleteness of the frames in t…

Hilbert space frames containing a Riesz basis and Banach spaces which have no subspace isomorphic to
Peter G. Casazza, Ole Christensen
We prove that a Hilbert space frame $\fti$ contains a Riesz basis if every subfamily $\ftj , J \subseteq I ,$ is a frame for its closed span. Secondly we give a new characterizatio…
