Abstract
In this paper, we show that one can develop a potential theory for brownian motion on every graded nilpotent simply connected Lie group and most of the classical results can be generalized in a natural way. In particular, we study the problem of Lebesgue thorn and the problem of recurrent and transient sets. We deduce also some asymptotic results concerning the area sweeped out by 2-dimensional brownian motion from the previous facts by considering the Heisenberg group.
