Isoperimetric inequality in noncompact MCP spaces

Metric Geometry 2021-11-12 v2 Functional Analysis

Abstract

We prove a sharp isoperimetric inequality for the class of metric measure spaces verifying the synthetic Ricci curvature lower bounds MCP(0,N)MCP(0,N) and having Euclidean volume growth at infinity. We avoid the classical use of the Brunn-Minkowski inequality, not available for MCP(0,N)MCP(0,N), and of the PDE approach, not available in the singular setting. Our approach will be carried over by using a scaling limit of localisation.
