Recently, we examined the order of $\\mathcal L^2$-convergence of the truncated SD method and showed that it can be arbitrarily close to $1/2,$ see \\textit{Stamatiou, Halidias (2019), Convergence rates of the Semi-Discrete method for stochastic differential equations, Theory of Stochastic Processes, 24(40)}. We show that the truncated SD method is able to preserve the asymptotic stability of the underlying SDE. Motivated by a numerical example, we also propose a different SD scheme, using the Lamperti transformation to the original SDE, which we call Lamperti semi-discrete (LSD). Numerical simulations support our theoretical findings.", "revisions": [ { "version": "v1", "updated": "2020-08-06T09:48:50.000Z" } ], "analyses": { "subjects": [ "60H10", "60H35", "65C20", "65C30", "65J15", "65L20" ], "keywords": [ "stochastic differential equations", "asymptotic stability", "semi-discrete method", "truncated sd method", "stochastic processes" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
