We investigate a new class of generalized backward doubly stochastic differential equations (GBDSDEs) driven by two independent Brownian motions and an independent Poisson random measure, which involves an integral with respect to a c\\`{a}dl\\`{a}g increasing process. We first derive existence and uniqueness of the solution of GBDSDEs with general jumps. We then introduce the definition of stochastic viscosity solutions of SIPDEs and give a probabilistic representation for stochastic viscosity solutions of semilinear SIPDEs with nonlinear Neumann boundary conditions. Finally, we establish stochastic maximum principles for the optimal control of a stochastic system modelled by a GBDSDE with general jumps.", "revisions": [ { "version": "v1", "updated": "2019-07-16T02:37:59.000Z" } ], "analyses": { "subjects": [ "60H15", "60H10", "93E20" ], "keywords": [ "stochastic viscosity solutions", "singular stochastic control", "doubly stochastic differential equations", "backward doubly stochastic differential", "semilinear stochastic integral-partial differential equations" ], "note": { "typesetting": "TeX", "pages": 47, "language": "en", "license": "arXiv", "status": "editable" } } }
