The Newman--Shapiro problem
Yurii Belov, Alexander Borichev
We give a negative answer to the Newman--Shapiro problem on weighted approximation for entire functions formulated in 1966 and motivated by the theory of operators on the Fock spac…
Univalent functions in model spaces: revisited
Anton Baranov, Yurii Belov, Alexander Borichev +1
Motivated by a problem in approximation theory, we find a necessary and sufficient condition for a model (backward shift invariant) subspace $K_\varTheta = H^2\ominus \varTheta H^2…
Summability properties of Gabor expansions
Anton Baranov, Yurii Belov, Alexander Borichev
We show that there exist complete and minimal systems of time-frequency shifts of Gaussians in which are not strong Markushevich basis (do not admit the spectral…
The Young type theorem in weighted Fock spaces
Anton Baranov, Yurii Belov, Alexander Borichev
We prove that for every radial weighted Fock space, the system biorthogonal to a complete and minimal system of reproducing kernels is also complete under very mild regularity assu…
