Szego limit theorems on the Sierpinski gasket
Kasso A. Okoudjou, Luke G. Rogers, Robert S. Strichartz
We use the existence of localized eigenfunctions of the Laplacian on the Sierpinski gasket to formulate and prove analogues of the strong Szego limit theorem in this fractal settin…
Frame potential and finite abelian groups
Brody D. Johnson, Kasso A. Okoudjou
This article continues a prior investigation of the authors with the goal of extending characterization results of convolutional tight frames from the context of cyclic groups to g…
A Beurling-Helson type theorem for modulation spaces
Kasso A Okoudjou
We prove a Beurling-Helson type theorem on modulation spaces. More precisely, we show that the only changes of variables that leave invariant the modulation space…
Invertibility of the Gabor frame operator on the Wiener amalgam space
Ilya A. Krishtal, Kasso A. Okoudjou
We use a generalization of Wiener's theorem to prove that for a Gabor frame with the generator in the Wiener amalgam space , the co…
