First, we introduce the notion of viscosity solution for the problem and construct certain discrete nonlinear approximation system. The existence and uniqueness of the solution of the discrete nonlinear system is proved. Based on that scheme, we propose projected Gauss-Seidel algorithm and prove its convergence. At the end of the paper we present some numerical simulations.", "revisions": [ { "version": "v1", "updated": "2014-07-03T04:45:24.000Z" } ], "analyses": { "keywords": [ "finite difference method", "two-phase obstacle problem", "numerical solution", "discrete nonlinear approximation system", "discrete nonlinear system" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1407.0781A" } } }
