在这篇文章中,我们在由广义Wallach空间产生的齐次流形上发现了几个新的非黎曼Einstein-Randers度量。我们首先证明了这些齐次流形上黎曼爱因斯坦度量的存在性。基于这些度量,我们证明了在这些齐次流形上存在非黎曼Einstein-Randers度量。
In this article, we find several new non-Riemannian Einstein-Randers metrics on some homogeneous manifolds arising from the generalized Wallach spaces. We first prove the existence of Riemannian Einstein metrics on these homogeneous manifolds. Based on these metrics, we prove that there exist non-Riemannian Einstein-Randers metrics on these homogeneous manifolds.
