Hyperinvariant subspaces for trace class perturbations of normal operators and decomposability

Eva A. Gallardo-GutiÃ©rrez, F. Javier GonzÃ¡lez-DoÃ±a

We prove that a large class of trace-class perturbations of diagonalizable normal operators on a separable, infinite dimensional complex Hilbert space have non-trivial closed hyper…

On commutants of composition operators embedded into $C_{0}$ -semigroups

F. Javier GonzÃ¡lez-DoÃ±a

Let $C_{I ¨} $ be a composition operator acting on the Hardy space of the unit disc $H^{p}$ ( $1 \leq p < \infty$ ), which is embedded in a $C_{0}$ -semigroup of composition operators $\mathca…
