This is a survey article on recent progress of comparison geometry and geometric analysis on Finsler manifolds of weighted Ricci curvature bounded below. Our purpose is twofold …
By using optimal mass transport theory we prove a sharp isoperimetric inequality in CD (0, N) metric measure spaces assuming an asymptotic volume growth at infinity. Our result …
The Lott-Sturm-Villani Curvature-Dimension condition provides a synthetic notion for a metric-measure space to have Ricci-curvature bounded from below and dimension bounded …

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 …
We consider a rigidity problem for the spectral gap of the Laplacian on an ${\rm RCD}(K,\infty) $-space (a metric measure space satisfying the Riemannian curvature …
