Exponential polynomials and identification of polygonal regions from Fourier samples

Mihail N. Kolountzakis, Emmanuil Spyridakis

Consider the set $E (D, N)$ of all bivariate exponential polynomials $f (I^¾, I^\cdot) = j = 1 \sum n p_{j} (I^¾, I^\cdot) e^{2 I ¨ i (x_{j} I^¾ + y_{j} I^\cdot)},$ where the polynomials $p_j \in \mathbb{C}[Î¾,…

Bounded lattice tiles that pack with another lattice

Sigrid Grepstad, Mihail N. Kolountzakis, Emmanuil Spyridakis

Suppose L and M are full-rank lattices in Euclidean space, such that vol(L) < vol(M). Answering a question of Han and Wang from 2001, we show how to construct a bounded measurable…
