Streszczenie
The Banach space $U(\mu )$ of uniformly convergent Fourier series with respect to an orthonormal polynomial sequence with orthogonalization measure $\mu $ supported on a compact set $S\subset {\mathbb R}$ is studied. For certain measures $\mu $, involving Bernstein–Szegö polynomials and certain Jacobi polynomials, it is proven that $U(\mu )$ has the Pełczyński property, and also that $U(\mu )$ and $U(\mu )^\star $ have the Dunford–Pettis property.
