摘要

In this paper, we establish several new inequalities for g-frames in Hilbert C*-modules which are different in structure from those previously obtained by Bakur et al. for linen space frames. We also present sonic equalities and inequalities for g-frames in Hilbert C*-modules with Moore-Penrose inverses and show that they are more general and cover some results in [Xiao, XC, Zeng, XM: Some properties of g-frarnes in Hilbert C*-modules. J. Math. Anal. Appl. 363 (2), 399-408 (2010)].
