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.

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 \(y\in X\).

Composition of linear canonical Hankel pseudo-differential operators

Asian-European Journal of Mathematics, 2023
In this paper, the study of linear canonical Hankel pseudo-differential operators has been extended to Sobolev-type spaces. Two versions of pseudo-differential operators involving linear canonical Hankel transformation are defined. We have shown that the pseudo-differential operators and composition of pseudo-differential operators are bounded in ...
