Moreover, we also prove the $L^1$-integrability and a general maximal principle for generalized solutions of SPDEs. As applications, we study nonlinear filtering problem and also obtain the existence and uniqueness of generalized solutions for a degenerate nonlinear SPDE.", "revisions": [ { "version": "v2", "updated": "2009-08-24T02:34:46.000Z" } ], "analyses": { "subjects": [ "60H15", "35K15" ], "keywords": [ "degenerate coefficients", "second order stochastic partial differential", "order stochastic partial differential equations", "linear second order stochastic partial", "degenerate nonlinear spde" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0908.2695Z" } } }
