Title:     Fourier and wavelet frame constructions and applications

Speaker:     John J. Benedetto, University of Maryland


     Two constructions are described. The first deals with Fourier
frames, and it solves a problem of constructing sampling sets on
interleaving spirals for the purpose of fast data acquisition in
Magnetic Resonance Imaging. The second deals with (dyadic) wavelet
frames, and it solves the problem of constructing single,
geometrically simple, frame wavelet sets in Euclidean space.
     Finite frames are used to implement the first construction.
The second construction leads to a paradigm associated with
Sigma-Delta quantization, which can also be addressed in terms of
finite frames.
