We show that the proposed method is a convergent regularization method. Numerical tests are presented for a linear problem related to photoacoustic tomography and a non-linear problem related to the testing of semiconductor devices.", "revisions": [ { "version": "v3", "updated": "2008-08-03T14:30:37.000Z" } ], "analyses": { "subjects": [ "65J20", "47J06" ], "keywords": [ "nonlinear ill-posed equations", "steepest-descent-kaczmarz methods", "regularizing systems", "convergent regularization method", "operator equations" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0801.3088D" } } }
