Gabor Frames of Totally Positive Functions: A Complete Characterization

Jaume de Dios Pont, Karlheinz Gröchenig, Lukas Liehr +2

We prove that the set of time-frequency shifts ${e^{2 π i β l t} g (t - α k) : k, l \in Z}$ with a continuous, integrable totally positive function $g$ and lattice parameters $α…

Quantitative Constraints for Stable Sampling on the Sphere

Martin Ehler, Karlheinz Gröchenig

We derive quantitative volume constraints for sampling measures $μ_{t}$ on the unit sphere $S^{d}$ that satisfy Marcinkiewicz-Zygmund inequalities of order $t$ . Using precise…
