On Positively Curved Einstein Four-Manifolds with Euler Characteristic at Most Three

Liang Cheng

It is conjectured that a complete, orientable Einstein four-manifold with strictly positive sectional curvature must be isometric to either the round four-sphere or the compl…

Ball and Spherical-Shell Rigidity from Overdetermined Translating Solitons

Liang Cheng, Li Ma

We study overdetermined boundary problems for the graphical translating-soliton equation \[ -\operatorname{div}\!\left(\frac{Du}{\sqrt{1+|Du|^2}}\right) =\frac{1}{\sqrt{1+|Du|^2}}…

On locally conformally flat manifolds with positive pinched Ricci curvature

Liang Cheng

By using the Yamabe flow, we prove that if , , is an -dimensional locally conformally flat complete Riemannian manifold , where is a uniform…

Pseudolocality theorems of Ricci flows on incomplete manifolds

Liang Cheng

In this paper we study the pseudolocality theorems of Ricci flows on incomplete manifolds. We prove that if a ball with its closure contained in an incomplete manifold has the smal…

Pseudolocality and uniqueness of Ricci flow on almost Euclidean noncompact manifolds

Liang Cheng, Yongjia Zhang

In this paper, we prove a pseudolocality-type theorem for -complete noncompact Ricci flow which may not have bounded sectional curvature; with the help of it we study t…

No breather theorems for the mean curvature flow

Liang Cheng, Yongjia Zhang

In this article we study the breathers of the mean curvature flow in the Euclidean space. A breather is a solution to the mean curvature flow which repeats itself up to isometry an…
