A New Characterization on g-frames in Hilbert C·-Modules

摘要

In this note, we establish a new characterization on g-frames in Hilbert C?-modules from the operator-theoretic point of view, with which we provide a cor-rection to one result recently obtained by Yao (Yao X Y. Some properties of g-frames in Hilbert C?-modules (in Chinese). Acta Math. Sinica, 2011, 54(1): 1-8.).
