Abstract:
In this paper,we discuss the following nonlinear reflected backward stochastic differential equation yt=ξ+∫t^Tf(s,ys,zs)ds-∫t^Tg(s,ys,zs)dws+KT-Kt,t∈[0,T]. We derive the existence and uniqueness of the solution of the above equation under non Lipschitz condition. The penalization method is our main method and the main tools are the extension of the Bihari inequality and the Yosida approximation of the subdifferential operator of the convex function.[著者文摘]
