Abstract

We prove the existence of maximal (and minimal) solution for one-dimensional generalized doubly reflected backward stochastic differential equation (RBSDE for short) with irregular barriers and stochastic quadratic growth, for which the solution Y has to remain between two rcll barriers L and U on [0,T[, and its left limit Y− has to stay respectively above and below two predictable barriers l and u on ]0,T]. This is done without assuming any P−integrability conditions and under weaker assumptions on the input data. In particular, we construct a maximal solution for such a RBSDE when the terminal condition ξ is only FT−measurable and the driver f is continuous with general growth with respect to the variable y and stochastic quadratic growth with respect to the variable z.
