Compact linear combinations of composition operators induced by linear fractional maps

Mathematische Zeitschrift, 2015
Let \(\Phi:\mathbb B_n\to \mathbb B_m\) be a holomorphic map from the unit ball in \(\mathbb C^n\) into the unit ball of \(\mathbb C^m\). It was shown that the composition operator \(C_\Phi(f)= f\circ \Phi\) is not necessarily bounded on Hardy spaces by \textit{C. C. Cowen} and \textit{B. D.

Adjoints of linear fractional composition operators on the Dirichlet space

open access: yesMathematische Annalen, 2003
Let \(T\) be an open unit disc on the complex plane and \(\mathcal{D}\) the Dirichlet space of functions analytic on \(T\) equipped with the norm defined by \[ \| f\| ^2=| f(0)| ^2+\int\limits_T| f^\prime(z)| ^2\,dA(z). \] The authors study the adjoints of the composition operators \(C_\varphi f= f\circ \varphi\) with a fractional linear function ...

On the convergence of sequences of positive linear operators towards composition operators

Banach Journal of Mathematical Analysis
Let \(F(X)\) be the linear space of real-valued functions on a metric space \((X,d)\), \(C_b(X)\) be the space of continuous bounded real-valued functions on \(X\), \(\left (d_x(\cdot)\right)_{x\in X}\) be a family of functions in \(F(X)\) such that for each \(x\in X\), we have \(d_x(y)=d(x,y)\) for \(y\in X\).

Cyclic behavior of linear fractional composition operators in the unit ball of CN

open access: yesJournal of Mathematical Analysis and Applications, 2008
We characterize the cyclicity and hypercyclicity of composition operators induced by linear fractional self-maps of BN on the Hardy space H2(BN) based on the classification of linear fractional maps given by Bisi and ...
