Abstract

Let (X,ω)({X}, \omega) be a compact nn-dimensional K\"ahler orbifold, the stabilizer groups of which are abelian and have rank at most two. Let E{E} be an orbi-ample vector bundle of rank 22 over X{X} and let HH be a Hermitian metric on E{E} such that the curvature form of detH\det H is 2π1ω-2\pi \sqrt{-1} \omega. We show that a certain weighted sum of Bergman kernels for SymiEdet(E)k+j{Sym}^i {E} \otimes \det({E})^{k+j} as ii and jj vary over a finite set admit an asymptotic expansion. This extends a similar result for cyclic K\"ahler orbifolds.
