The scheme involves two types of errors: one generated by application of the Euler-Maruyama scheme and the other ascribed to simulation of the inverse subordinator. With the two errors carefully examined, the orders of strong and weak convergence are derived. Numerical examples are attached to support the convergence results.", "revisions": [ { "version": "v1", "updated": "2014-08-19T16:10:13.000Z" } ], "analyses": { "subjects": [ "60H10", "60H35", "65C30" ], "keywords": [ "stochastic differential equations driven", "time-changed brownian motion", "weak approximation scheme", "general inverse subordinator" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1408.4377J" } } }
