Yl. Tian et Wp. Zhang, AN ANALYTIC PROOF OF THE GEOMETRIC-QUANTIZATION CONJECTURE OF GUILLEMIN-STERNBERG, Inventiones Mathematicae, 132(2), 1998, pp. 229-259
We present a direct analytic approach to the Guillemin-Sternberg conje
cture [GS] that 'geometric quantization commutes with symplectic reduc
tion', which was proved recently by Meinrenken [M1], [M2] and Vergne [
V1], [V2] et al. Besides providing a new proof of this conjecture, our
methods also lead immediately to further extensions in various contex
ts.
