On the Parity Under Metapletic Operators and an Extension of a Result of Lyubarskii and Nes
In this work we show that if the frame property of a Gabor frame with window in Feichtinger’s algebra and a fixed lattice only depends on the parity of the window, then the lattice can be replaced by any other lattice of the same density without losing the frame property. As a byproduct we derive a...
