-positivity and a classification of closed three-dimensional CR torsion solitons
Huai-Dong Cao, Shu-Cheng Chang, Chih-Wei Chen
A closed CR 3-manifold is said to have -positive pseudohermitian curvature if for any . We discover an obstruction for a closed…
Volume bounds of the Ricci flow on closed manifolds
Chih-Wei Chen, Zhenlei Zhang
Let be the solution of the Ricci flow on a closed Riemannian manifold with . Without any assumption, we derive lower volume bounds of the for…
Level set flow in 3D steady gradient Ricci solitons
Chih-Wei Chen, Kuo-Wei Lee
Let be a nontrivial 3-dimensional steady gradient Ricci soliton. If the scalar curvature satisfies for some ,…
On the CR Analogue of Reilly Formula and Yau Eigenvalue Conjecture
Shu-Cheng Chang, Chih-Wei Chen, Chin-Tung Wu
In this paper, we derive the CR Reilly's formula and its applications to studying of the first eigenvalue estimate for CR Dirichlet eigenvalue problem and embedded p-minimal hypers…
Structure at infinity of expanding gradient Ricci soliton
Chih-Wei Chen, Alix Deruelle
We study the geometry at infinity of expanding gradient Ricci solitons of dimension greater than two with finite asymptotic curvature ratio without curvature sign assumptions. We m…
Volume estimates and the asymptotic behavior of expanding gradient Ricci solitons
Chih-Wei Chen
We study the asymptotic volume ratio of non-steady gradient Ricci solitons. Moreover, a local estimate of the volume ratio is obtained for expanding solitons which satisfy $\lim_{d…
