We prove continuous dependence of the compensated solutions X(t)-e^{tA}X_0 in the norms L^p(\\Omega;C^\\lambda([0,T];E)) assuming that the approximating operators A_n are uniformly sectorial and converge to A in the strong resolvent sense, and that the approximating nonlinearities F_n and G_n are uniformly Lipschitz continuous in suitable norms and converge to F and G pointwise. Our results are applied to a class of semilinear parabolic SPDEs with finite-dimensional multiplicative noise.", "revisions": [ { "version": "v2", "updated": "2011-02-09T15:30:06.000Z" } ], "analyses": { "subjects": [ "60H15", "47D06" ], "keywords": [ "semilinear stochastic partial differential equations", "approximating", "semilinear stochastic evolution equations", "coefficients", "semilinear parabolic spdes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1003.1876K" } } }
