A note on perturbations of Fusion Frames
Abstract
In this work, we consider some relationships between a closed range operator T and a fusion frame W=(Wi,wi)i∈ I for a Hilbert space H that provides that the sequence (T(Wi),vi)i∈ I is a fusion frame sequence for H, if we consider a suitable family of weights \vi\i∈ I. This (sufficient) condition generalizes some previous work in the subject.
