    In a new paper on the arxiv,

    Group averaging, positive definiteness and
    superselection sectors1

    the technique of quantizing with a non-compact Lie group called Group Averaging is discussed with regard to when (so far as is now known) it leads to meaningful results or otherwise. As will be recalled from several threads, GA is a sometimes controversial tool in attempts to quantize gravity, used by Thiemann, Rovelli, and others.

    From Louko's conclusion:
