Alexandrov–Fenchel inequalities for convex hypersurfaces in the half-space with capillary boundary

G Wang, L Weng, C Xia - Mathematische Annalen, 2024 - Springer
In this paper, we first introduce quermassintegrals for capillary hypersurfaces in the half-
space. Then we solve the related isoperimetric type problems for the convex capillary …

Locally constrained inverse curvature flows

We consider inverse curvature flows in warped product manifolds, which are constrained
subject to local terms of lower order—namely, the radial coordinate and the generalized …

Rigidity results, inverse curvature flows and Alexandrov-Fenchel type inequalities in the sphere

Hyperbolic -sum and Horospherical -Brunn-Minkowski theory in hyperbolic space

H Li, B Xu - arXiv preprint arXiv:2211.06875, 2022 - arxiv.org
The classical Brunn-Minkowski theory studies the geometry of convex bodies in Euclidean
space by use of the Minkowski sum. It originated from H. Brunn's thesis in 1887 and H …
