    Week 1 (Morning)
    Tencent Meeting: 457-6962-6473 Password: 7374 .

    Speaker: Xuan Yao (Princeton University)

    Title: Capillary minimal slicing and scalar curvature rigidity in dimension $4$
    Abstract: We develop a capillary minimal slicing technique and as a result, we prove a scalar curvature rigidity result in dimension $4$.

    Week 6 (Afternoon)
    Tencent Meeting: 457-6962-6473 Password: 7374 .

    Speaker: Sun Yukai (Henan University)

    Title: Warped area-minimizing hypersurface and warped product metric
    Abstract: We first review the related conclusions about the splitting into product metric for area-minimizing hypersurfaces under some proper conditions. Then we discuss the basic knowledge of warped area-minimizing hypersurfaces. At last, we can prove that the metric is locally splitting into a warped product metric under the condition of spectral curvature.
