对于维为$2n+1$,$n\geq 2$的紧致CR流形$(X,T^{1,0}X)$,允许$S^1\次T^d$作用,如果格点$(-p_1,\cdots,-p_d)$(-p_1,\cdots,-p_d)\是相关CR矩映射$\mU$的正则值,则建立了环面等变Szegő核$\pI^{(0)}_{m,MP_1,\cdots,MP_d}(x,Y)$作为$m\to+\inty$,在一定的假设下,在$Y:=\mu^{-1}(-p_1,\cdots,-p_d)$上的Levi形式和环面作用下。
For a compact CR manifold $(X,T^{1,0}X)$ of dimension $2n+1$, $n\geq 2$, admitting a $S^1\times T^d$ action, if the lattice point $(-p_1,\cdots,-p_d)\in\mathbb{Z}^{d}$ is a regular value of the associate CR moment map $\mu$, then we establish the asymptotic expansion of the torus equivariant Szegő kernel $\Pi^{(0)}_{m,mp_1,\cdots,mp_d}(x,y)$ as $m\to +\infty$ under certain assumptions of the positivity of Levi form and the torus action on $Y:=\mu^{-1}(-p_1,\cdots,-p_d)$.
