Zusammenfassung

In this talk, we firstly introduce a capillary John ellipsoid theorem for capillary convex bodies in the Euclidean half-space \(\overline{\mathbb{R}^{n+1}_{+}}\). This theorem yields a non-collapsing estimate for capillary hypersurfaces, which provides a new approach to obtaining \(C^{0}\) estimates for solutions to some capillary curvature problems (including the capillary \(L_{p}\) Christoffel–Minkowski problem and the capillary \(L_{p}\) curvature problem). Then, as a further application, we study the capillary \(L_{p}\) dual Minkowski problem, establish existence for \(1<p\leq q\leq 3\), and improve existing results for the case \(p>q\) in \(\overline{\mathbb{R}^{3}_{+}}\).

Zusammenfassung

In this talk, I will introduce a new notion of convexity in the unit sphere called horo-convexity, inspired by its analogue in hyperbolic space. For horo-convex hypersurfaces, we prove the smooth convergence of the Guan/Li inverse curvature flow and, as a consequence, establish the full set of quermassintegral inequalities on the sphere. If time permits, I will also discuss parallel results for the hypersurface with capillary boundary lying in the Euclidean unit ball. This talk is based on joint works with Julian Scheuer.
