Abstract
We prove a generalization with sharp constants of a classical inequality due to Hardy to Carnot groups of arbitrary step, or more general Carnot-Carathéodory spaces associated with a system of vector fields of Hörmander type. Under a suitable additional assumption (see Eq. 1.6 below) we are able to extend such result to the nonlinear case p ne; 2. We also obtain a sharp inequality of Hardy-Sobolev type. © 2010 Springer Science+Business Media B.V.
