摘要
We prove an optimal reverse Poincare inequality for the heat semigroup generated by the sub-Laplacian on a Carnot group of any step. As an application we give new proofs of the isoperimetric inequality and of the boundedness of the Riesz transform in Carnot groups. (C) 2015 Elsevier Ltd. All rights reserved.
