WEIGHTED RIESZ BASES IN G-FUSION FRAMES AND THEIR PERTURBATION
In this paper, we introduce orthonormal and Riesz bases for g-fusion frames and show that the weights have basic roles. Next, we prove an effective theorem between frames and g-fusion frames by using an operator. Finally, perturbations of g-fusion frames will be presented.
