Variational approach to the asymptotic mean-value property for the p-Laplacian on Carnot groups

Abstract

Let $1<p \leq \infty$. We provide an asymptotic characterization of continuous viscosity solutions $u$ of the normalized $p$-Laplacian $\Delta_{p\,\mathbb{G}}^N u=0$ in any Carnot group $\mathbb{G}$.
