On the Hamilton-Tian Conjecture in a compact transverse Fano Sasakian -manifold

Shu-Cheng Chang, Yingbo Han, Chien Lin +1

In this paper, we first confirm the Hamilton-Tian conjecture for the Sasaki-Ricci flow in a compact transverse Fano quasi-regular Sasakian -manifold with klt foliation singulari…

On the Sasakian Structure of Manifolds with Nonnegative Transverse Bisectional Curvature

Shu-Cheng Chang, Yingbo Han, Chien Lin +1

In this paper, we concern with the Sasaki analogue of Yau uniformization conjecture in a complete noncompact Sasakian manifold with nonnegative transverse bisectional curvature. As…

Gradient Shrinking Sasaki-Ricci Solitons with Harmonic Weyl Tensor

Shu-Cheng Chang, Hongbing Qiu

We establish integral curvature estimates for complete gradient shrinking Sasaki-Ricci solitons. As an application, we show that any such soliton with harmonic Weyl tensor must be…

Geometry and Topology of Gradient Shrinking Sasaki-Ricci Solitons

Shu-Cheng Chang, Yingbo Han, Chin-Tung Wu

In this paper, we study the geometry and topology of complete gradient shrinking Sasaki-Ricci solitons. We first prove that they must be connected at infinity. This is a Sasaki ana…

Contact Blow-up Analysis of the Legendrian Mean Curvature Flow and a Smale-type Theorem for Strict Contactomorphisms of Sasakian Spheres

Shu-Cheng Chang, Chin-Tung Wu, Liuyang Zhang

We study the Legendrian mean curvature flow in -Einstein Sasakian manifolds by parabolic rescalings which preserve the contact structure. In a compact -Einstein Sasakian mani…
