These are obtained as the lower semicontinuous and convex envelope of a cost for non-negative Dirac masses. New general primal-dual formulations, optimality conditions, and metric-topological properties are carefully studied and discussed.", "revisions": [ { "version": "v1", "updated": "2023-12-31T17:08:20.000Z" } ], "analyses": { "subjects": [ "49Q22", "28A33", "49K27" ], "keywords": [ "monge formulation", "relaxation viewpoint", "optimality", "general convex relaxation approach", "unbalanced optimal transport problems" ], "note": { "typesetting": "TeX", "pages": 57, "language": "en", "license": "arXiv", "status": "editable" } } }
