Entropy of Compact Operators with Applications to Landau-Pollak-Slepian Theory and Sobolev Spaces

Thomas Allard, Helmut Bölcskei

Published 2024-06-08Version 1

We derive a precise general relation between the entropy of a compact operator and its eigenvalues. It is then shown how this result along with the underlying philosophy can be applied to improve substantially on the best known characterizations of the entropy of the Landau-Pollak-Slepian operator and the metric entropy of unit balls in Sobolev spaces.
