Abstract :
In this paper we get some results and applications for duals and approximate
duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and
approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of Hilbert spaces. We also obtain some results for perturbations of approximate duals.
