| Abstract: | The recurrence and transience of Brownian motion on Rie mannian manifolds were considered. The first part of the paper was set out to prove that alternative is true on complete Riemannian manifolds with non-negative Ricci curvature and to acquire the condition in which Brownian motion is recurrent. The second part was to obtain the sufficient and necessary condition for Brownian motion being recurrent on Riemann surfaces. |
