In this paper we introduce a new numerical scheme which is closer to the classical Euler scheme for diffusion processes, in the sense that it has the rate of convergence $2H-\\frac12$. In particular, the rate of convergence becomes $\\frac 12$ when $H$ is formally set to $\\frac 12$ (the rate of Euler scheme for classical Brownian motion). The rate of weak convergence is also deduced for this scheme. The main tools are fractional calculus and Malliavin calculus. We also apply our approach to the classical Euler scheme.", "revisions": [ { "version": "v1", "updated": "2013-06-06T16:24:41.000Z", "comment": null, "journal": null, "doi": null }, { "version": "v2", "updated": "2017-03-04T04:45:13.000Z" } ], "analyses": { "keywords": [ "stochastic differential equations driven", "fractional brownian motion", "modified euler approximation scheme", "classical euler scheme" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1306.1458H" } } }
