Note on the backwards uniqueness of mean curvature flow
Zhuhong Zhang
In this note, we will show a backwards uniqueness theorem of the mean curvature flow with bounded second fundamental form in arbitrary codimension.
Four-dimensional Einstein manifolds with sectional curvature bounded from above
Zhuhong Zhang
Given an Einstein structure with positive scalar curvature on a four-dimensional Riemannian manifolds, that is for some positive constant . For convenience, the Ricci c…
A gap theorem of four-dimensional gradient shrinking solitons
Zhuhong Zhang
In this paper, we will prove a gap theorem for four-dimensional gradient shrinking soliton. More precisely, we will show that any complete four-dimensional gradient shrinking solit…
Local pinching estimates in 3-dim Ricci flow
Bing-Long Chen, Guoyi Xu, Zhuhong Zhang
We study curvature pinching estimates of Ricci flow on complete 3- dimensional manifolds without bounded curvature assumption. We will derive some general curvature conditions whic…
Gradient Shrinking Solitons with Vanishing Weyl Tensor
Zhu-Hong Zhang
In this paper, we will give a local version of the Hamilton-Ivey type pinching estimate of the gradient shrinking soliton with vanishing Weyl tensor, and then give a complete class…
On the Completeness of Gradient Ricci Solitons
Zhu-Hong Zhang
A gradient Ricci soliton is a triple satisfying for some real number . In this paper, we will show that the completeness of the met…
