Equivariant Asymptotics of Szegő kernels under Hamiltonian SU(2)-actions

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