I will give an expository account of Mathai, Melrose, and Singer
[math.DG/0402329], explaining how to define the projective Dirac "operator" when
the underlying manifold is neither spin nor spin_C, and how to define its
analytic index which need not be an integer. Nevertheless, the usual index
formulas apply.
Professor Singer will be admitted as honorary member of the London
Mathematical Society just before his talk.
