Torus Equivariant Szegő Kernel Asymptotics on Strongly Pseudoconvex CR Manifolds
Hendrik Herrmann , Chin-Yu Hsiao , Xiaoshan Lipp. 113-135
Abstract
Let (X,T^{1,0}X) be a compact strongly pseudoconvex CR manifold of dimension $2n+1$. Assume that a $d$-dimensional torus $T^d$ acts on $X$. In this work, we study the behavior of torus equivariant Szegő kernels and prove that the weighted torus equivariant Szegő kernels admit asymptotic expansions.
