球面上的一个完全非线性流与quermass积分不等式

A fully-nonlinear flow and quermassintegral inequalities in the sphere

Chuanqiang Chen, Pengfei Guan, Junfang Li, Julian Scheuer

摘要:

本文介绍了目前的知识,特别是完全非线性曲率流的局部强迫项,所谓的局部约束曲率流。我们专注于球形环境空间。这些流被设计为保留一个quermassintegral,并减少/增加其他quermassintegral。这个流收敛到一个圆形的球将解决的凸区域的球的quermass积分不等式的全部集合,但一个完整的证明仍然缺乏。在这里,我们收集了已知的,并希望引起广泛关注这个有趣的问题。

英文摘要:

This expository paper presents the current knowledge of particular fully nonlinear curvature flows with local forcing term, so-called locally constrained curvature flows. We focus on the spherical ambient space. The flows are designed to preserve a quermassintegral and to de-/increase the other quermassintegrals. The convergence of this flow to a round sphere would settle the full set of quermassintegral inequalities for convex domains of the sphere, but a full proof is still missing. Here we collect what is known and hope to attract wide attention to this interesting problem.
