摘要：Some equalities for frames involving the real parts of some complex numbers have been recently established in [P. Gavruta, On some identities and inequalities for frames in Hilbert spaces. J. Math. Anal. Appl., 321 (2006) 469-478]. In the current note, we generalize the equalities to a more general form which does not involve the real parts of the complex numbers. (C) 2010 Elsevier Ltd.
