In the case of $\\alpha$-H\\\"older drift in recent literature the rate $\\alpha/2$ was proved in many related situations. By exploiting the regularising effect of the noise more efficiently, we show that the rate is in fact arbitrarily close to $1/2$ for all $\\alpha>0$. The result extends to Dini continuous coefficients, while in $d=1$ also to a class of everywhere discontinuous coefficients.", "revisions": [ { "version": "v1", "updated": "2018-12-11T18:10:27.000Z" } ], "analyses": { "subjects": [ "60H35", "60H10", "65C30" ], "keywords": [ "euler-maruyama scheme", "regularisation", "irregular drift coefficients", "nondegenerate sdes", "strong rate" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
