Waist inequality for 3-manifolds with positive scalar curvature

Differential Geometry 2023-01-18 v4 Metric Geometry

Abstract

We construct singular foliations of compact three-manifolds (M3,h)(M^3,h) with scalar curvature RhΛ0>0R_h\geq \Lambda_0>0 by surfaces of controlled area, diameter and genus. This extends Urysohn and waist inequalities of Gromov-Lawson and Marques-Neves.
