A unified approach to $L^p$ Hardy and Rellich-type inequalities in Euclidean and non-Euclidean settings (2401.04504v1)

Abstract: In this paper we introduce a unified and compact method for proving $L^p$ Hardy and Rellich-type inequalities. The most important feature of our method is that it allows us to extend these inequalities beyond the traditional Euclidean setting. More precisely, the applications of this method span diverse contexts, including the Heisenberg group, general Carnot groups, and operators represented as the sum of squares of vector fields. Notable examples include the sub-Laplacian on Carnot groups, the Heisenberg-Greiner operator, and the Baouendi-Grushin operator.
