Secondly, we introduce a new type of inverse spectral problem, posed as follows: for a priori given potential $V_0$ find the closest function $\\hat{V}$ such that $m$ eigenvalues of one-dimensional space Schrodinger operator with potential $\\hat{V}$ would coincide with the given values $ E_1 $, $ \\ldots $, $ E_m \\in \\mathbb {R} $. In our main result, we prove the existence of a solution to this problem, and more importantly, we show that such a solution can be directly found by solving a system of nonlinear differential equations.", "revisions": [ { "version": "v1", "updated": "2019-08-21T13:56:53.000Z" } ], "analyses": { "subjects": [ "34B15", "65R32", "74J25" ], "keywords": [ "schrödinger operator", "optimal potential", "nonlinear differential equations", "eigenvalue", "one-dimensional space schrodinger operator" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
