Abstract
This paper concerns the existence of nontrivial solutions of the RiemannโHilbert problem with a continuous coefficient whose values belong to two rays in the complex plane. Our results extend those recently obtained by E. Shargorodsky and J. F. Toland [6]. (ยฉ 2004 WILEYโVCH Verlag GmbH & Co. KGaA, Weinheim)

The concept of a moment map for an action of a real Lie group by CR -diffeomorphisms on a CR -manifold M of hypersurface type is introduced. It gives rise to a natural reduction procedure in the sense that we construct a CR -structure on an associated orbit manifold M 0 for the case that the group a
