We study the approximation of jump-diffusion SDEs with non-adaptive as well as jump-adapted approximation schemes and provide lower error bounds of order $3/4$ for both classes of approximation schemes. This yields optimality of the transformation-based jump-adapted quasi-Milstein scheme.", "revisions": [ { "version": "v2", "updated": "2023-03-21T13:46:31.000Z" } ], "analyses": { "subjects": [ "65C30", "65C20", "60H10", "68Q25" ], "keywords": [ "jump-diffusion sdes", "discontinuous drift", "optimality", "jump-diffusion stochastic differential equations", "sharp lower error bounds" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
