Fredholm weighted composition operators

Integral Equations and Operator Theory, 1993
We characterize the Fredholm weighted composition operators onC(X). In particular, ifX is a set with some regular property like intervals or balls inR n , our characterization implies that a weighted composition operator is Fredholm if and only if it is invertible.

Weighted Composition Operators on Weighted Dirichlet Spaces

Acta Mathematica Scientia, 2013
We characterize the boundedness and compactness of weighted composition operators on weighted Dirichlet spaces in terms of Nevanlinna counting functions and Carleson measure.

Dynamics of Weighted Composition Operators

Complex Analysis and Operator Theory, 2012
We study the dynamic behaviour of weighted composition operators on the space of holomorphic functions on a simply connected plane domain and endowed with the compact open topology. Any such operator is weakly supercyclic if and only if it is topologically mixing and, when the weight is bounded, if and only if the operator has a hypercyclic subspace ...

Eigenvalues of Adjoints of Certain Composition Operators and Weighted Composition Operators [PDF]

Integral Equations and Operator Theory, 2014
We look at the point-spectrum of the adjoints of certain composition operators on the Hardy–Hilbert space, for which the composition map has two distinguished fixed points: one inside the unit disk and one on the unit circle. In particular, we show that the point-spectrum of such operators contains a disk centered at the origin, and each eigenvalue in ...
