The Szeg\"O kernel on an orbifold circle bundle
Abstract
The analysis of holomorphic sections of high powers LN of holomorphic ample line bundles L M over compact K\"ahler manifolds has been widely applied in complex geometry and mathematical physics. The Tian-Yau-Zelditch's asymptotic expansion of the Szeg\"o kernel of a circle bundle plays an important role in K\"ahler-Einstein geometry. We generalize the expansion for compact K\"ahler orbifolds with only finite isolated singularities and analyze the behavior of the expansion near the singularities.
