A logarithmic renormalisation is required to counterbalance the divergent product appearing in the equation. Furthermore, we use time-dependent weights in our spaces of distributions in order to construct the solution on the unbounded space $\\mathbf{R}^2$.", "revisions": [ { "version": "v1", "updated": "2015-01-04T16:26:04.000Z" } ], "analyses": { "keywords": [ "continuum parabolic anderson model", "simple construction", "time-dependent weights", "elaborate arguments", "divergent product" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150100692H" } } }
