| Abstract: | In this paper, we study the relationship between frames for the super Hilbert space H⊕H and g-frames for H with respect to C2. We show that a g-frame associated with a frame for H⊕H remains a g-frame whenever any one of its elements is removed. Furthermore, we show that the excess of such a g-frame is at least dimH. |
