Minimal Invariant Subspaces for an Affine Composition Operator
Complex Analysis and Operator Theory, 2023The composition operator $$C_{\phi _a}f=f\circ \phi _a$$ C ϕ a f = f ∘ ϕ a on the Hardy–Hilbert space $$H^2({\mathbb {D}})$$ H 2 ( D ) with affine symbol $$\phi _a(z)=az+1-a$$ ϕ a ( z ) = a z + 1 - a and ...

Integral equations and operator theory
We analyse the behaviour of the iterates of composition operators defined by polynomials acting on global classes of ultradifferentiable functions of Beurling type which are invariant under the Fourier transform.

On the Berezin range of Toeplitz and weighted composition operators on weighted Bergman spaces
Complex Analysis and Operator TheoryIn this article, we completely characterize the Berezin range of Toeplitz operators with harmonic symbols acting on weighted Bergman spaces, illustrating the necessity of the harmonicity condition through examples.

Fredholm composition operators on Banach spaces of holomorphic functions
Journal of operator theoryLet B(Ω) be a Banach space of holomorphic functions on a\break bounded connected domain Ω in Cn, which contains the ring of polynomials on Ω. Under suitable assumptions on Ω and B(Ω), we establish a characterization of the composition operator and the ...
