Consider the Lie group SO0(n, 1) with the left-invariant metric coming from the Killing-Cartan form. The maximal compact subgroup SO(n) of the isometry group acts from the left and right. This paper studies the geometry of the quotient space of the homogeneous submersion SO0(n, 1) → SO(n)\SO0(n, 1). It is a cohomogeneity one manifold, which can be expressed as a warped product. Its group of isometries, geodesics, and sectional curvatures are calculated. 相似文献

In this paper we show that any properly convex quasi-homogeneous affine domain with irreducible projective automorphism group is projectively equivalent to a homogeneous affine domain. Then as an application we answer positively the Markus conjecture when the manifold M is in a certain class of convex affine manifolds.Mathematics Subject Classification (1991): 51M10, 57S25This work was supported by Korea Research Foundation Grant (KRF-2002-070-C00010).in final form: 6 October 2003 相似文献
