We define a discounted value function associated to this problem and show that the value function is a viscosity solution to a certain HJB equation in $\\mathbb{R}_+$ with nonlinear Neumann type boundary condition. Under certain conditions, we also characterize this value function as the unique solution to this HJB equation.", "revisions": [ { "version": "v1", "updated": "2015-09-03T15:04:44.000Z" } ], "analyses": { "subjects": [ "93E20", "60H30", "35J25", "49L25" ], "keywords": [ "hjb equation", "viscosity solution", "state constraints", "reflection control", "value function" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150901118B" } } }
