Abstract: Conjectural formulas are given expressing the genus zero Gromov-Witten invariants of the quotient of a complex projective manifold $ X$ by a reductive group $ G$ (the nonabelian quotient) in terms of the invariants of the quotient by a maximal torus $ T$ (the abelian quotient). The ``$ J$-function'' version of the formulas is proved when $ X$ is a (generalized) flag manifold.
