  • Abstract
    Given any two almost orthonormal systems A and A of unit vectors in a Hilbert space X of the same cardinality, there exists a norm preserving almost isometry F of X so that F(A) = A. It follows that to every almost orthonormal system there corresponds a system of almost coefficient functionals. © 2005 Elsevier Inc. All rights reserved.
