Lifting mappings over invariants of finite groups
Abstract
We characterize those regular, holomorphic or formal maps into the orbit space V/G of a complex representation of a finite group G which admit a regular, holomorphic or formal lift to the representation space V. In particular, the case of complex reflection groups is investigated.
