Abstract
We consider the following quasi-linear parabolic system of backward partial differential equations on a Banach space E: (∂t + L)u + f(·,·,u, A1/2∇ u) = 0 on [0,T] × E, uT = φ, where L is a possibly degenerate second-order differential operator with merely measurable coefficients. We solve this system in the framework of generalized Dirichlet forms and employ the stochastic calculus associated to the Markov process with generator L to obtain a probabilistic representation of the solution u by solving the corresponding backward stochastic differential equation. The solution satisfies the corresponding mild equation which is equivalent to being a generalized solution to the PDE. A further main result is the generalization of the martingale representation theorem in infinite dimension using the stochastic calculus associated to the generalized Dirichlet form given by L. The non-linear term f satisfies a monotonicity condition with respect to u and a Lipschitz condition with respect to ∇u.

I would like to thank Professor Michael Röckner for valuable discussions and for suggesting associate BSDE's to generalized Dirichlet forms which was one motivation for this paper. I would also like to thank Professor Ma Zhiming and Zhu Xiangchan for their helpful discussions.
