The fiberization of affine systems via dual Gramian techniques, which was
developed in previous papers of the authors, is applied here for the study of
affine frames that have an affine dual system. Gramian techniques are also used
to verify whether a dual pair of affine frames is also a pair of bi-orthogonal
Riesz bases. A general method for a painless derivation of a dual pair of affine
frames f... hiện toàn bộ
