Reproducing kernel Riesz bases associated to real points in model subspaces K I = H 2 IH of the Hardy space H have been described in terms of equality of spaces by A. Baranov [1]. We now answer the question of whether the natural analogue of his result with the real points being replaced by sequences of points located in the whole complex plane holds. It turns out that the analogous conditions are indeed sufficient but not in general necessary. A consequence of this is that larger perturbations… 


Completeness and Riesz bases of reproducing kernels in model subspaces
We use the recent approach of N. Makarov and A. Poltoratski to give a criterion of completeness of systems of reproducing kernels in the model subspaces KΘ = H 2aΘH2 of the Hardy class H. As an
Discrete Hilbert transforms on sparse sequences
Weighted discrete Hilbert transforms (an)n ↦ ∑n an vn/(z−γn) from ℓ2ν to a weighted L2‐space are studied, with Γ=(γn) a sequence of distinct points in the complex plane and v=(vn) a corresponding
On Fourier frames
We solve the problem of Duffin and Schaeffer (1952) of characterizing those sequences of real frequencies which generate Fourier frames. Equivalently, we characterize the sampling sequences for the
