Stability of dual $g$-fusion frames in Hilbert spaces


We give a characterization of K-g-fusion frames and discuss the stability of dual g-fusion frames. We also present a necessary and sufficient condition for a quotient operator to be bounded.

Надається характерізація K-g фреймів злиття та розглядається стійкисть двоїстих g-фпеймів злиття. Також надаються необхідні та достатні умови обмеженності оператора факторизації.

Key words: g-fusion frame, K-g-fusion frame, stability of a frame, quotient operator.
