WEIGHTED COMPOSITION OPERATORS BETWEEN LORENTZ SPACES

Bulletin of the Australian Mathematical Society, 2020
AbstractWe investigate the boundedness, compactness, invertibility and Fredholmness of weighted composition operators between Lorentz spaces. It is also shown that the classes of Fredholm and invertible weighted composition maps between Lorentz spaces coincide when the underlying measure space is nonatomic.

Dynamics of Weighted Composition Operators

Complex Analysis and Operator Theory, 2012
In the paper under review, the author is concerned with the dynamics of the weighted composition operator \(C_{\omega,\varphi}: H(\Omega)\to H(\Omega)\) given by \(C_{\omega,\varphi}(f)(z)=\omega(z)(f\circ \varphi)(z)\), for \(z\in \Omega\), where \(H(\Omega)\) denotes the space of holomorphic functions on a simply connected domain \(\Omega\) of the ...

Fredholm weighted composition operators

Integral Equations and Operator Theory, 1993
For a compact Hausdorff space \(X\) and some functional space \(F(X)\) on \(X\) a weighted composition operator is defined as \(uC_ \varphi f(x):=u(x)f(\varphi (x))\), where \(\varphi: X\to X\) is an automorphism. The author obtains criteria for the operator \(uC_ \varphi: C(X)\to C(X)\) to be a Fredholm operator and finds that in the case when \(X ...

WEIGHTED COMPOSITION OPERATORS BETWEEN WEIGHTED BLOCH TYPE SPACES

Mathematical Proceedings of the Royal Irish Academy, 2011
Summary: Let \(\mathbb{D}\) be the open unit disk in the complex plane and \(\varphi:\mathbb{D}\to\mathbb{D}\) as well as \(\psi:\mathbb{D}\to\mathbb{C}\) be analytic maps. For a holomorphic function \(f\) on \(\mathbb{D}\), the weighted composition operator \(C_{\varphi,\psi}\) is defined by \((C_{\varphi,\psi} f)(z)=\psi(z)f(\varphi(z))\) for every \(
