Transverse Rigidity of Shrinking Sasaki-Ricci Solitons

Shu-Cheng Chang, Fengjiang Li, Chien Lin +1

In this paper, we study several properties of Sasaki-Ricci solitons as singularity models of the Sasaki-Ricci flow. First, we establish several fundamental equations for Sasaki-Ric…

Quasi-Einstein manifolds with Harmonic Weyl curvature

Huai-Dong Cao, Fengjiang Li, James Siene

In this paper, we classify $n$ -dimensional ( $n \geq 5$ ) quasi-Einstein manifolds with harmonic Weyl curvature, thus extending the work of Shin \cite{Shin} in dimension four for quas…

Rigidity of Five-dimensional Shrinking Gradient Ricci Solitons with Constant Scalar Curvature

Fengjiang Li, Jianyu Ou, Yuanyuan Qu +1

Let $(M, g, f)$ be a $5$ -dimensional complete noncompact gradient shrinking Ricci soliton with the equation $R i c + \nabla^{2} f = I^» g$ , where $Ric$ is the Ricci tensor and $\nabla…

Rigidity of Five-Dimensional shrinking gradient Ricci solitons

Fengjiang Li, Jianyu Ou, Yuanyuan Qu +1

Suppose $(M, g, f)$ is a 5-dimensional complete shrinking gradient Ricci soliton with $R = 1$ . If it has bounded curvature, we prove that it is a finite quotient of $\mathbb{R}^3\tim…
