Abstract: Approximately dual frames as a generalization of duality notion in Hilbert spaces have applications in Gabor systems, wavelets, coorbit theory and sensor modeling. In recent years, the computing of the associated deviations of the canonical… read more here.

Abstract: This paper deals with structural issues concerning wavelet frames and their dual frames. It is known that there exist wavelet frames {aj/2ψ(aj · −kb)}j,k∈Z in L2(R) for which no dual frame has wavelet structure. We… read more here.
