Abstract
One of the most important problems in the studying of frames and its extensions is the invariance of these systems under perturbation. In this paper, we first give a result concerning perturbations of K–g-frames and then use it to construct K–g-frames in Hilbert spaces. We also characterize the concept of K–g-frames by quotient maps.
