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