Resumen
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.
