Abstract

We establish the existence of weak solutions for a decoupled system of a forward stochastic differential equation (SDE) and a backward stochastic differential equation (BSDE). The generator H ( x , y , z ) is assumed continuous in ( y , z ) but possibly discontinuous in x. The drift of the forward component is merely measurable drift and the diffusion coefficient can be discontinuous. Our approach is based on partial differential equations.
