J. Franchi, ASYMPTOTIC WINDINGS OF BROWNIAN-MOTION IN A COMPACT RIEMANN MANIFOLD OF DIMENSION-3, Stochastic processes and their applications, 52(2), 1994, pp. 251-272
Let M be a Riemannian compact manifold of dimension 3, X its Brownian
motion, ($) over cap M a compact submanifold of codimension 2, and ome
ga a closed 1-form on M' = M\($) over cap M; then the Stratonovitch in
tegral t(-1) integral(0)(t) omega(X(s)) converges in law towards a Cau
chy variable.
