Minimal Norm Interpolation in Harmonic Hilbert Spaces and Wiener Amalgam Spaces on Locally Compact Abelian Groups
Hans G. Feichtinger, Sheel S. Pandey, Tobias Werther
The family of harmonic Hilbert spaces is a natural enlargement of those classical -Sobolev space on which consist of continuous functions. In the present paper we dem…
