Erasures and perturbations of g-frames and fusion frames in Hilbert C*-modules

In this paper, we study the erasures of submodules of a fusion frame in Hilbert C*-modules and we present some sufficient conditions under which a sequence remains a standard fusion frame after deletion of some submodules. We also introduce a new perturbation for g-frames and fusion frames in Hilbert C*-modules and it is shown that under some conditions g-frames and fusion frames are stable under this perturbation. We generalize some of the results obtained for perturbations of g-frames and fusion frames, especially we consider perturbations of direct sums, duals and approximate duals of g-frames.
