We treat this equation in an abstract framework, in which parabolic stochastic partial differential equations are also included as a special case. The approximation in space is performed by a standard finite element method and in time by an implicit Euler method combined with a convolution quadrature. The weak rate of convergence is proved to be twice the strong rate, as expected. Our weak convergence result concerns not only the solution at a fixed time but also integrals of the entire path with respect to any finite Borel measure. The proof does not rely on a Kolmogorov equation. Instead it is based on a duality argument from Malliavin calculus.", "revisions": [ { "version": "v1", "updated": "2014-11-24T14:59:42.000Z" } ], "analyses": { "subjects": [ "60H15", "60H07", "65C30", "65M60" ], "keywords": [ "semilinear stochastic volterra equations", "weak error analysis", "stochastic partial differential equations", "stochastic volterra integro-differential equation", "volterra integro-differential equation driven" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1411.6476A" } } }
