Homogeneous Lorentz Manifolds with Simple Isometry Group
Let H be a closed, noncompact subgroup of a simple Lie group G, such that G/H admits an invariant Lorentz metric. We show that if G = SO(2, n), with n ≥ 3, then the identity component H of H is conjugate to SO(1, n). Also, if G = SO(1, n), with n ≥ 3, then H is conjugate to SO(1, n− 1).
متن کاملThe Geometry of Compact Homogeneous Spaces with Two Isotropy Summands
We give a complete list of all homogeneous spaces M = G/H where G is a simple compact Lie group, H a connected, closed subgroup, and G/H is simply connected, for which the isotropy representation of H on TpM decomposes into exactly two irreducible summands. For each homogeneous space, we determine whether it admits a G-invariant Einstein metric. When there is an intermediate subgroup H < K < G,...
متن کاملAlmost Homogeneous Manifolds with Boundary
In this article we study the classification of some Lie group actions on differentiable manifolds, up to conjugacy. Let us start with the precise notion of conjugacy we shall use. Two C r actions ρ1, ρ2 of a Lie group G on a manifold M are said to be C r conjugate if there is a C r diffeomorphism Φ : M → M that is (ρ1, ρ2) equivariant, that is: Φ(ρ1(g)x) = ρ2(g)Φ(x) ∀x ∈ M ∀g ∈ G. A conjugacy c...
متن کاملCompact Lorentz manifolds with local symmetry
We prove a structure theorem for compact aspherical Lorentz manifolds with abundant local symmetry. If M is a compact, aspherical, real-analytic, complete Lorentz manifold such that the isometry group of the universal cover has semisimple identity component, then the local isometry orbits in M are roughly fibers of a fiber bundle. A corollary is that if M has an open, dense, locally homogeneous...
متن کاملInvariant Einstein Metrics on Flag Manifolds with Four Isotropy Summands
A generalized flag manifold is a homogeneous space of the form G/K, where K is the centralizer of a torus in a compact connected semisimple Lie group G. We classify all flag manifolds with four isotropy summands by the use of t-roots. We present new G-invariant Einstein metrics by solving explicity the Einstein equation. We also examine the isometric problem for these Einstein metrics. 2000 Mat...
