题目1: Isometry groups of compact manifolds with indefinite metric II

摘要:Part II focuses on isometry groups of compact homogeneous manifolds with an invariant indefinite metric.  If the index of the metric is small, we explain that a complete classification of such manifolds is possible. We will also introduce the basic result that every compact homogeneous space with a transitive solvable group of isometries is isometric to a quotient  of  a solvable Lie group with a biinvariant metric. The proof of the latter result relies on a combination of density properties for uniform subgroups of solvable Lie groups and the reduction theory of  metric Lie groups.
