Let U be a unipotent group over the field of complex numbers C, acting on acomplex algebraic variety X. Assume that there exists a surjective morphism ofcomplex algebraic varieties f: X --> Y whose fibres are orbits of U. We showthat if X and Y are smooth and all orbits of U in X have the same dimension,then the induced map on C-points X(C) --> Y(C) is a homotopy equivalence.Moreover, if U, X, Y, and f are defined over the field of real numbers R, thenthe induced map on R-points X(R) --> Y(R) is surjective and induces homotopyequivalences on connected components.

Taking quotient by a unipotent group induces a homotopy equivalence
