We give a constructive proof of a uniqueness result by Kenig, Sj\\\"ostrand, and Uhlmann. We construct a uniquely specified family of solutions such that their traces on the boundary can be calculated by solving an integral equation which involves only the given partial Cauchy data. The construction entails a new family of Green's functions for the Laplacian, and corresponding single layer potentials, which may be of independent interest.", "revisions": [ { "version": "v2", "updated": "2009-08-27T18:28:29.000Z" } ], "analyses": { "subjects": [ "35R30" ], "keywords": [ "partial data", "calderon problem", "reconstruction", "partial cauchy data", "corresponding single layer potentials" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0904.4794N" } } }
