The coefficients $F$ and $G$ are assumed to satisfy the usual monotonicity and coercivity conditions. In the case of a cylindrical L\\'evy process with finite second moments, we derive the result without further assumptions. For the case of cylindrical L\\'evy processes without finite moments, we consider a subclass containing numerous examples from the literature. Deriving the existence result in the latter case requires a careful analysis of the jumps of cylindrical L\\'evy processes.", "revisions": [ { "version": "v1", "updated": "2018-07-30T16:11:13.000Z" } ], "analyses": { "subjects": [ "60H15", "60G51", "60G20", "28A35" ], "keywords": [ "stochastic partial differential equations", "cylindrical levy process", "cylindrical lévy noise", "variational solutions", "stochastic evolution equation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
