Spectral synthesis for exponentials and logarithmic length
Anton Baranov, Yurii Belov, Aleksei Kulikov
We study hereditary completeness of systems of exponentials on an interval such that the corresponding generating function is small outside of a lacunary sequence of intervals…

Backward shift and nearly invariant subspaces of Fock-type spaces
Alexandru Aleman, Anton Baranov, Yurii Belov +1
We study the structure of the backward shift invariant and nearly invariant subspaces in weighted Fock-type spaces , whose weight is not necessarily radial. We…

Upper and lower densities of Gabor Gaussian Systems
Yurii Belov, Alexander Borichev, Alexander Kuznetsov
We study the upper and the lower densities of complete and minimal Gabor Gaussians systems. In contrast to the classical lattice case when they are both equal to , we prove that…
