双曲和球面空间中的球腰

Waist of balls in hyperbolic and spherical spaces

Arseniy Akopyan, Roman Karasev

摘要:

本文给出了常曲率空间中球的Gromov腰的一个紧估计,导出了曲率有上界的黎曼流形($\mathrm{CAT}(κ)$ -空间)中球的估计,并在赋范空间中建立了类似的结果.

英文摘要:

In this paper we find a tight estimate for Gromov's waist of the balls in spaces of constant curvature, deduce the estimates for the balls in Riemannian manifolds with upper bounds on the curvature ($\mathrm{CAT}(κ)$-spaces), and establish similar result for normed spaces.
