摘要
Stiefel manifolds VqRn of all orthonormal q-frames in R-n are diffeomorphic to the homogeneous space SO(n)/SO(n - q). In this paper, we prove that there exist at least four homogeneous Einstein-Randers metrics on SO(n)/SO(n - 4) (n >= 6), Moreover, we get at least six homogeneous Einstein-Randers metrics on SO(7)/SO(2).
