The cost functional contains a term that measures the size of the support of the control, which is the so-called $L^0$-norm. We provide necessary and sufficient optimality conditions of second-order. The sufficient second-order condition is obtained by analyzing a partially convexified problem. Interestingly, the structure of the problem yields second-order conditions with different bilinear forms for the necessary and for the sufficient condition.", "revisions": [ { "version": "v1", "updated": "2020-02-12T11:20:15.000Z" } ], "analyses": { "subjects": [ "35J61", "49K20", "40J52" ], "keywords": [ "cost functional", "semilinear elliptic partial differential equations", "problem yields second-order conditions", "optimal control problems subject", "sufficient second-order condition" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
