The Turán and Delsarte problems and their duals
Mihail N. Kolountzakis, Nir Lev, Máté Matolcsi
We study two optimization problems for positive definite functions on Euclidean space with restrictions on their support and sign: the Turan problem and the Delsarte problem. These…
Geometric implications of weak tiling
Mihail N. Kolountzakis, Nir Lev, Máté Matolcsi
The notion of weak tiling played a key role in the proof of Fuglede's spectral set conjecture for convex domains, due to the fact that every spectral set must weakly tile its compl…
Unconditional Schauder frames of exponentials and of uniformly bounded functions in spaces
Nir Lev, Anton Tselishchev
It is known that there is no unconditional basis of exponentials in the space , , for any set of finite measure. This is a consequence of a…
Completeness of sparse, almost integer and finite local complexity sequences of translates in
Nir Lev, Anton Tselishchev
A real sequence is called -generating if there exists a function whose translates span the space . Whi…
