Expansivity and shadowing for composition operators on Paley-Wiener spaces

Carlos F. Álvarez, O. R. Severiano

In this article, we study composition operators $C_{ϕ} f = f \circ ϕ$ on the full range of Paley-Wiener spaces $B_{a}^{2}$ for $a > 0.$ Here we compute the spectrum and the spectral radius of…

Dynamics for affine composition operators on weighted Bergman space of a half plane

Artur Blois, Osmar R. Severiano

In this article, we completely characterize the positive expansive and absolutely Cesàro composition operators $C_{ϕ} f = f \circ ϕ$ induced by affine self-maps $ϕ$ of the right half-pla…
