Resumo

We consider an epsilon K transversal perturbing vector field in a foliated Brownian motion defined in a foliated tubular neighbourhood of an embedded compact submanifold in R-3. We study the effective behaviour of the system under this epsilon perturbation. If the perturbing vector field K is proportional to the Gaussian curvature at the corresponding leaf, we have that the transversal component, after rescaling the time by t/epsilon, approaches a linear increasing behaviour proportional to the Euler characteristic of M, as epsilon goes to zero. An estimate of the rate of convergence is presented. (AU)
