I will present a paper by Malikiosis (2015), which generalized the result that (Lawrence, Pfander, Walnut 2005) a Gabor frame in prime dimension with almost every window function is a frame maximally robust to erasures, by proving that this is also true for every finite dimension. The paper also provides a general method of constructing such Gabor frames whose window function has bounded magnitudes in each coordinate.
