As a consequence any sufficiently often differentiable curve in the orbit space $V/G$ can be lifted twice differentiably. These results can be generalized to arbitrary polar representations. Finite reflection groups and finite rotation groups in dimensions two and three are discussed in detail.19 pages, LatexRepresentation TheoryClassical Analysis and ODEs22E45; 20F55text
