Research Abstract |
We established a framework for studying left-invariant Riemannian metrics on Lie groups in terms of submanifold geometry. As applications, we have obtained a general procedure to get Milnor-type theorems, and a characterization of algebraic Ricci solitons in terms of submanifold geometry in three-dimensional cases. We have also studied homogeneous submanifolds in noncompact symmetric spaces, and obtained a classification of hyperpolar foliations and a rough classification of cohomogeneity one actions. Results on geometric properties of some particular submanifolds have also been obtained.
