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

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

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

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…

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 $C_{ϕ} f = f \circ ϕ$ on the Paley-Wiener spaces of entire functions $B_{σ}^{2}$ for $σ > 0$ . We show that $C_{ϕ}$ …

Complex symmetry of linear fractional composition operators on a half-plane

V. V. Fávaro, P. V. Hai, O. R. Severiano

We investigate the bounded composition operators induced by linear fractional self-maps of the right half-plane $C_{+}$ on the Hardy space $H^{2} (C_{+}) .$ We completely…

Composition operators on Hardy-Smirnov spaces

V. V. Fávaro, P. V. Hai, D. M. Pellegrino +1

We investigate composition operators $C_{Φ}$ on the Hardy-Smirnov space $H^{2} (Ω)$ induced by analytic self-maps $Φ$ of an open simply connected proper subset $Ω$ of the complex plan…

Complex symmetric weighted composition operators on Bergman spaces and Lebesgue spaces

Pham Viet Hai, Osmar R. Severiano

In the paper, we investigate weighted composition operators on Bergman spaces of a half-plane. We characterize weighted composition operators which are hermitian and those which ar…

Interplay between complex symmetry and Koenigs eigenfunctions

S. Waleed Noor, Osmar R. Severiano

We investigate the relationship between the complex symmetry of composition operators $C_{ϕ} f = f \circ ϕ$ induced on the classical Hardy space $H^{2} (D)$ by an analytic self-map…

Complex symmetry of composition operators on weighted Bergman spaces

Osmar R. Severiano

In this article, we study the complex symmetry of compositions operators $C_{ϕ} f = f \circ ϕ$ induced on weighted Bergman spaces $A_{β}^{2} (D), β \geq - 1,$ by analytic self-maps of…
