For a general Carnot group $G$ with homogenous dimension $Q$ we prove the existence of a fundamental solution of the $Q$-Laplacian whose exponential is a homogenous norm on $G$. This implies a sharp version of the celebrated Moser-Trudinger inequality.

Keywords: Carnot group, Q-Laplacian , Fundamental solution, Moser-Trudinger inequality
