Abstract

Let MM be complex projective manifold, and AA a positive line bundle on it. Assume that SU(2)SU(2) acts on MM in a Hamiltonian manner, with nowhere vanishing moment map, and that this action linearizes to AA. Then there is an associated unitary representation of GG on the associated algebro-geometric Hardy space, and the isotypical components are all finite dimensional. We consider the local and global asymptotic properties the equivariant projector associated to a weight kνk \, \boldsymbol{ \nu }, when ν\boldsymbol{ \nu } is fixed and k+k\rightarrow +\infty.
