Spectral clumping for functions decreasing rapidly on a half-line

Bartosz Malman

We demonstrate a phenomenon of condensation of the Fourier transform $f$ of a function $f$ defined on the real line $R$ which decreases rapidly on one half of th…

Shift operators, Cauchy integrals and approximations

Bartosz Malman

This article consists of two connected parts. In the first part, we study the shift invariant subspaces in certain $P^{2} (μ)$ -spaces, which are the closures of analytic pol…

Revisiting mean-square approximation by polynomials in the unit disk

Bartosz Malman

For a positive finite Borel measure $μ$ compactly supported in the complex plane, the space $P^{2} (μ)$ is the closure of the analytic polynomials in the Lebesgue space $L^2…
