Nonnegative Ricci curvature and the Brownian coupling property. (English) Zbl 0584.58045
This paper shows that if $$M$$ is a complete Riemannian manifold with Ricci curvatures all nonnegative then $$M$$ has the Brownian coupling property. From this one may immediately draw deductions concerning the nonexistence of certain harmonic maps.
