Abstract:
      The aim of this article is to discuss a volume nullification property of the diffusion process determined by a stochastic differential equation on a manifold. Let Xt(x) be a diffusion process describing a flow of diffeomorphisms x→Xt (x) in a manifold M, and K be a compact surface in M with positive finite Hausdorff measure. We present conditions under which the area of Xt(K) goes to zero almost surely and in moments as t→∞, in particular, the flow Xt(·) asymptotic nullifies the arc-lenth of oriented rectifiable arcs r:[0,1]→M.
