Abstract

The aim of this paper is to obtain some estimate for largetime for the Heatkernel corresponding to a sub-Laplacian with drift term on a nilpotentLiegroup. We also obtain a uniform Harnack inequality for a “bounded” family of sub-Laplacians with drift in the first commutator of the Lie algebra of the nilpotentgroup.
