We proved that the singularities of the viscosity solution of \\eqref{eq:discount 1} propagate along locally Lipschitz singular characteristics which can extend to $+\\infty$. We also obtained the homotopy equivalence between the singular set and the complement of associated the Aubry set with respect to the viscosity solution of equation \\eqref{eq:discount 1}.", "revisions": [ { "version": "v1", "updated": "2021-06-03T02:03:08.000Z" } ], "analyses": { "keywords": [ "discounted hamilton-jacobi equation", "global propagation", "singularities", "viscosity solution", "time-dependent evolutionary hamilton-jacobi equation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
