T&G: Yael Karshon (Toronto), Old fashioned geometric quantization

I will review the Kostant-Souriau geometric quantization procedure for passing from functions on a symplectic manifold (classical observables) to operators on a Hilbert space (quantum observables). With the "half-form correction" that is required in this procedure, one cannot quantize a complex projective space of even complex dimension, and one cannot equivariantly quantize the two-sphere nor any symplectic toric manifold. I will present a geometric quantization procedure that uses metaplectic-c structures to incorporate the half-form correction into the earlier prequantization stage and that does apply to these examples. This follows work of Harald Hess from the late 1970s with recent contributions of Jennifer Vaughan.
