On a length preserving curve flow
Li Ma, Anqiang Zhu
In this paper, we consider a new length preserving curve flow for convex curves in the plane. We show that the global flow exists, the area of the region bounded by the evolving cu…

Nonsingular Ricci flow on a noncompact manifold in dimension three
Li Ma, Anqiang Zhu
We consider the Ricci flow on the 3-dimensional complete noncompact manifold with non-negative curvature operator, i.e., $Rm\geq 0,…

Eigenvalues and lambda constants on Riemannian submersions
Li Ma, Anqiang Zhu
Given a Riemannian submersion, we study the relation between lambda constants introduced by G.Perelman on the base manifold and the total space of a Riemannian submersion. We also…
