Abstract

Controlled \ast-K-fusion frames are generalization of controlled fusion frames in frame theory. In this paper, we propose the notion of controlled \ast-k-fusions frames on Hilbert CC^{\ast}-modules. We give some caraterizations and some of their properties are obtained. Then we study the erasures of submodules of a controlled kk-fusion frame in Hilbert CC^{\ast}-modules and we present some sufficient conditions under which a sequence remains a standart controlled k-fusion frame after deletion of some submodules. Finally, we introduce a perturbation for controlled KK-fusion frames in Hilbert CC^{\ast}-modules and it is shown that under some conditions controlled KK-fusion frames are stable under this perturbation, and we generalize some of the results obtained for perturbations of controlled KK-fusion frames.
