T1 Hyperinvariant subspaces for trace class perturbations of normal operators and decomposability
A1 Gallardo Gutiérrez, Eva Antonia
A1 González-Doña, F. Javier
AB 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 hyperinvariant subspaces. Moreover, a large subclass consists of decomposable operators in the sense of Colojoara and Foias.
