Rigidity of conformal metrics with constant sixth-order $Q$ -curvature

Daowen Lin, Wangzhe Wu

Let $(M^{n}, g_{0})$ be a closed connected Einstein manifold with positive scalar curvature, where $n \geq 6$ . Using an Obata-type identity, we prove that every smooth metric conformal to…

A sharp threshold for mixed $Q$ -curvature rigidity

Wangzhe Wu

We resolve Case's question (Crelle's Journal, 2024) on the sharp lower threshold for Obata-type rigidity of $I_{a} = Q + a σ_{2} (A)$ in positive Einstein conformal classes of dimension $n\g…

Rigidity, sharp inequalities, and stability for $σ_{2}$ -curvature by a reference curvature technique

Wangzhe Wu

Using a reference-curvature technique, we prove four main theorems. (i) For $n \geq 4$ , we remove the mean-curvature pinching from the Case-Wang rigidity theorem for $σ_{2}$ -flat confo…
