Weighted normalized curve shortening flow with applications in pseudo-Euclidean spaces
Baichuan Hu, Xiang Ma
The focus of this paper is the curve shortening flow for closed spacelike curves in pseudo-Euclidean spaces, which has very few results so far. Will they produce singularities wher…
Möbius Homogeneous Hypersurfaces in
Tongzhu Li, Xiang Ma, Changping Wang +1
Let denote the Möbius transformation group of the -dimensional sphere . A hypersurface is called…
Can One Perturb the Equatorial Zone on a Sphere with Larger Mean Curvature?
Baichuan Hu, Xiang Ma, Shengyang Wang
We consider the mean curvature rigidity problem of an equatorial zone on a sphere which is symmetric about the equator with width . There are two different notions on rigidity,…
Mean Curvature Rigidity and Non-rigidity Results on Spherical Caps
Shibing Chen, Xiang Ma, Shengyang Wang
We prove that a hemisphere in the Euclidean space , viewed as the graph of a function, admits no smooth perturbations as graphs with mean curvature whose boundary…
Closed strong spacelike curves, Fenchel theorem and Plateau problem in the 3-dimensional Minkowski space
Nan Ye, Xiang Ma
We generalize the Fenchel theorem for strong spacelike closed curves of index in the 3-dimensional Minkowski space, showing that the total curvature must be less than or equal…
The Fenchel-type inequality in the 3-dimensional Lorentz space and a Crofton formula
Nan Ye, Xiang Ma, Donghao Wang
We generalize the Fenchel theorem to strong spacelike (which means that the tangent vector and the curvature vector span a spacelike 2-plane at each point) closed curves with index…
