Translation surfaces in Lie groups with constant Gaussian curvature
Xu Han, Zhonghua Hou
Let G be a n-dimensional Lie group (n>2) with a bi-invariant Riemannian metric. We prove that if a surface of constant Gaussian curvature in G can be expressed as the product of tw…

Mean curvature flow solitons from symmetry group viewpoint
Xu Han, Zhonghua Hou
The symmetry group of the mean curvature flow in general ambient Riemannian manifolds is determined, based on which we define generalized solitons to the mean curvature flow. We al…
