In this equation, the noise is multiplied by a Lipschitz function $\\sigma(u)$ of the solution. We assume that the spatial dimension is $d=1$ or $d=2$. Under general conditions on the L\\'evy measure of the noise, we prove the existence of the solution, and we show that, as a function-valued process, the solution has a c\\`adl\\`ag modification in the local fractional Sobolev space of order $r<1/4$ if $d=1$, respectively $r<-1$ if $d=2$.", "revisions": [ { "version": "v2", "updated": "2023-01-31T21:54:26.000Z" } ], "analyses": { "keywords": [ "stochastic wave equation", "lévy white noise", "space-time levy white noise", "local fractional sobolev space", "infinite variance" ], "note": { "typesetting": "TeX", "pages": 36, "language": "en", "license": "arXiv", "status": "editable" } } }
