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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
