We show both uniqueness results and the convergence of an iteration scheme designed to recover these coefficients. We also allow a more general setting, in particular when the usual time derivative is replaced by one of fractional order and when the potential term is coupled with a known nonlinearity $f$ of the form $q(x)f(u)$.", "revisions": [ { "version": "v1", "updated": "2019-05-29T06:09:54.000Z" } ], "analyses": { "subjects": [ "35R30", "65M32", "35R11" ], "keywords": [ "multiple coefficients", "reaction-diffusion equation", "solution profiles taken", "inverse problem", "parabolic equation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
