摘要:Let G' subset-of G be real reductive Lie groups and q a theta-stable parabolic subalgebra of Lie (G) x C. This paper offers a sufficient condition on (G, G', q) that the irreducible unitary representation A(q)BAR of G with non-zero continuous cohomology splits into a discrete sum of irreducible unitary representations of a subgroup G', each of finite multiplicity. As an application to purely analytic problems, new results on discrete series are also obtained for some pseudo-Riemannian (non-sym...

摘要:Let Q be a circle domain in the Riemann sphere C whose boundary has sigma-finite linear measure. We show that OMEGA is rigid in the sense that any conformal homeomorphism of Q onto any other circle domain is equal to the restriction of a Mobius transformation. Previously, Kaufman and Bishop have independently found examples of non-rigid circle domains whose boundary is a Cantor set of (Hausdorff) dimension one.

摘要:The subject of this paper is the problem of topological arrangement of real algebraic curves on real algebraic surfaces. In this paper I extend Rokhlin, Kharlamov-Gudkov-Krakhnov and Kharlamov-Marin congruences and give some applications of this extension. Among these applications there are new restrictions for topological arrangement of real algebraic curves of a given degree on hyperboloid and ellipsoid, new restrictions for complex orientations of curves on a hyperboloid and the topological...
