Shadowing phenomenon for composition operators on the Hardy space $H^{2} (D)$

Artur Blois, Ben-Hur Eidt, Paulo Lupatini +1

Let $I ¨ $ be a holomorphic self-map of the open unit disk $D .$ In this article, we study the shadowing phenomenon for composition operators $C_{I ¨} f = f \circ I ¨ $ on the Hardy s…

Expansivity and shadowing for composition operators on Paley-Wiener spaces

Carlos F. Ãlvarez, O. R. Severiano

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

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 CesÃ ro composition operators $C_{I ¨} f = f \circ I ¨ $ induced by affine self-maps $I ¨ $ of the right half…

Cyclicity of composition operators on the Paley-Wiener spaces

Pham Viet Hai, Waleed Noor, Osmar Reis Severiano

In this article we characterize the cyclicity of bounded composition operators $C_{I ¨} f = f \circ I ¨ $ on the Paley-Wiener spaces of entire functions $B_{I ¨}^{2} $ for $I ¨ > 0$ . We show that $C…
