Tensor fields and connections on holomorphic orbit spaces of finite groups

Abstract

For a representation of a finite group GG on a complex vector space VV we determine when a holomorphic (pq)\binom{p}{q}-tensor field on the principle stratum of the orbit space V/GV/G can be lifted to a holomorphic GG-invariant tensor field on VV. This extends also to connections. As a consequence we determine those holomorphic diffeomorphisms on V/GV/G which can be lifted to orbit preserving holomorphic diffeomorphisms on VV. This in turn is applied to characterize complex orbifolds.
