In this paper, we introduce an extension of this property, called Fej\\'er* monotonicity, which was initially proposed in [SIAM J. Optim., 34(3), 2535-2556 (2024)]. We discuss and build upon the concept by exploring its behavior within Hilbert spaces, presenting an illustrative example and insightful results regarding weak and strong convergence. We also compare Fej\\'er* monotonicity with other weak notions of Fej\\'er-like monotonicity, to better establish the role of Fej\\'er* monotonicity in optimization algorithms.", "revisions": [ { "version": "v1", "updated": "2024-10-10T19:42:40.000Z" } ], "analyses": { "subjects": [ "49M27", "65K05", "65B99", "90C25" ], "keywords": [ "optimization algorithms", "weak notions", "fejer monotonicity", "strong convergence", "insightful results regarding weak" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
