Divergence theorems in path space II: degenerate diffusions

چکیده
Let x denote an elliptic diffusion process defined on a smooth compact manifold M . In a previous work, we introduced a class of vector fields on the path space of x and studied the admissibility of this class of vector fields with respect to the law of x. In the present note, we extend this study to the case of degenerate diffusions. Résumé Laisser x indique un diffusion elliptique défini sur un lisse compact variété M . Dans un travail précédent, nous avons introduit une classe de champs de vecteur sur l’espace de chemin de x et a étudié le admissibilté de cette classe de champs de vecteur par rapport à la loi de x. Dans la note présente, nous étendons cette étude au cas de diffusions dégénérées. 1Research partially supported by NSF grant DMS-0451194.

Divergence theorems in path space III: hypoelliptic diffusions and beyond∗
Let x denote a diffusion process defined on a closed compact manifold. In an earlier article, the author introduced a new approach to constructing admissible vector fields on the space of paths associated to x, under the assumption that x is elliptic. In this article, this method is extended to yield similar results for degenerate diffusion processes. In particular, these results apply to non-e...
متن کاملCentral limit theorems for additive functionals of ergodic Markov diffusions processes
We revisit functional central limit theorems for additive functionals of ergodic Markov diffusion processes. Translated in the language of partial differential equations of evolution, they appear as diffusion limits in the asymptotic analysis of FokkerPlanck type equations. We focus on the square integrable framework, and we provide tractable conditions on the infinitesimal generator, including...
متن کاملDivergence Theorems in Path Space
We obtain divergence theorems on the solution space of an elliptic stochastic differential equation defined on a smooth compact finite-dimensional manifold M . The resulting divergences are expressed in terms of the Ricci curvature of M with respect to a natural metric on M induced by the stochastic differential equation. The proofs of the main theorems are based on the lifting method of Mallia...
متن کاملOn homogenization of space-time dependent and degenerate random flows II
We study the long time behavior (homogenization) of a diffusion in random medium with time and space dependent coefficients. The diffusion coefficient may degenerate. In Stochastic Process. Appl. (2007) (to appear), an invariance principle is proved for the critical rescaling of the diffusion. Here, we generalize this approach to diffusions whose space-time scaling differs from the critical one...
متن کاملVariational inequalities in Hilbert spaces with measures and optimal stopping
We study the existence theory for parabolic variational inequalities in weighted L spaces with respect to excessive measures associated with a transition semigroup. We characterize the value function of optimal stopping problems for finite and infinite dimensional diffusions as a generalized solution of such a variational inequality. The weighted L setting allows us to cover some singular cases...
