"Moment map images of Borel orbits"

Abstract: Atiyah has proved that the moment map image of the closure of a complex torus orbit is convex. Brion generalized this result to actions of a complex reductive group. We extend part of their work to actions of a maximal solvable subgroup. (Joint with Victor Guillemin.)
