The integral is constructed using a novel technique that utilizes the radonification of cylindrical martingales by a Hilbert-Schmidt operator theorem. We apply the developed theory of stochastic integration to establish existence and uniqueness of weak and mild solutions for stochastic evolution equations driven by multiplicative cylindrical martingale-valued measure noise with rather general coefficients. Our theory covers the study of integration and of SPDEs driven by Hilbert space valued L\\'{e}vy noise (which is not required to satisfy any moment condition), cylindrical L\\'{e}vy noise with (weak) second moments and L\\'{e}vy-valued random martingale measures with finite second moment.", "revisions": [ { "version": "v1", "updated": "2020-01-24T16:39:43.000Z" } ], "analyses": { "subjects": [ "60H05", "60H15", "60B11", "60G20" ], "keywords": [ "stochastic integration", "hilbert space", "stochastic pdes", "cylindrical martingale-valued measure noise", "stochastic evolution equations driven" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
