Overcompleteness of coherent frames for unimodular amenable groups

. This paper concerns the overcompleteness of coherent frames for amenable unimodular groups. It is shown that for coherent frames associated with an integrable vector a set of positive Beurling density can be removed yet still leave a frame. The obtained results extend various theorems of [J. Fourier Anal. Appl., 12(3):307-344, 2006] to frames with non-Abelian index sets.
