Endpoint Absolute Monotonicity for the Complete Elliptic Integral of the First Kind

Qintao Deng, Yunjia Kou, Fulin Zhong

Let \begin{equation*} f_p(x)=\frac{\mathcal{K}(\sqrt{x})}{p-\ln\sqrt{1-x}}, \end{equation*} where $K$ denotes the complete elliptic integral of the first kind, and set $g…

On the Rigidity of Closed CMC Hypersurfaces in $S^{5} (1)$ with Constant Scalar Curvature

Qintao Deng, Yunjia Kou

Let $M^{4} ↪ S^{5} (1)$ be a closed CMC hypersurface with constant scalar curvature and constant third power sum $f_{3} = \sum_{i, j, k} h_{ij} h_{j k} h_{k i}$ . We prove that…

Closed Minimal Hypersurfaces in $S^{5} (1)$ with Constant Scalar and Gauss-Kronecker Curvatures

Qintao Deng, Yunjia Kou

In this paper, we prove that any closed minimal hypersurface $M^{4}$ of $S^{5} (1)$ with constant scalar curvature and constant Gauss-Kronecker curvature must be isoparametric.…

Topology of two-dimensional collapsed spaces with lower Ricci bounds

Elia Bruè, Qin Deng

We prove that collapsed metric measure spaces with Ricci curvature bounded below and essential dimension two are topological surfaces, possibly with boundary.
