E. Pardoux et Sg. Peng, BACKWARD DOUBLY STOCHASTIC DIFFERENTIAL-EQUATIONS AND SYSTEMS OF QUASI-LINEAR SPDES, Probability theory and related fields, 98(2), 1994, pp. 209-227
We introduce a new class of backward stochastic differential equations
, which allows us to produce a probabilistic representation of certain
quasilinear stochastic partial differential equations, thus extending
the Feynman-Kac formula for linear SPDE's.
