Kernel Theorems in Coorbit Theory
Peter Balazs, Karlheinz Gröchenig, Michael Speckbacher
We prove general kernel theorems for operators acting between coorbit spaces. These are Banach spaces associated to an integrable representation of a locally compact group and cont…
Gabor Frames: Characterizations and Coarse Structure
Karlheinz Gröchenig, Sarah Koppensteiner
This survey offers a systematic and streamlined exposition of the most important characterizations of Gabor frames over a lattice. The goal is to collect the most important charact…
Compactness Criteria in Function Spaces
Monika Dörfler, Hans G. Feichtinger, Karlheinz Gröchenig
The classical criterion for compactness in Banach spaces of functions can be reformulated into a simple tightness condition in the time-frequency domain. This description preserves…
