Compact standard periodic einstein manifolds

Abstract

A Riemannian manifold \(M\) with a metric \(g\) is Einstein if its metric \(g\) satisfies the equation: \(\text{Ric}(g)=Cg\), where Ric is the Ricci tensor of \(M\) and \(C\) is a constant. Let \(G\) be a connected, compact simple Lie group and \(H\) its closed simple subgroup with \(G/H\) simply connected. The homogeneous Riemannian metric induced on \(G/H\) by the Killing form of the Lie algebra of \(G\) is referred to as the standard homogeneous metric. In this paper, the author gives a complete classification of compact, simply connected, standard homogeneous, periodic Einstein manifolds, i.e. manifolds whose transitive groups of motions are not simple, but instead, at each point of a manifold there exists a symmetry of finite order. It turns out that each such manifold is isometric to a symmetric, compact space or to the Riemannian product of spaces of special type.

Keywords

symmetric space, Special Riemannian manifolds (Einstein, Sasakian, etc.), Differential geometry of homogeneous manifolds, periodic Einstein manifolds, Killing form, standard homogeneous metric
