We prove moment stability of the discretised processes and a strong convergence rate of 1/2. We present several numerical examples centred around a mean-field model for FitzHugh-Nagumo neurons, which illustrate that the standard uniform scheme fails and that the adaptive scheme shows in most cases superior performance compared to tamed approximation schemes. In addition, we propose a tamed and an adaptive Milstein scheme for a certain class of McKean SDEs.", "revisions": [ { "version": "v1", "updated": "2020-05-12T20:12:50.000Z" } ], "analyses": { "keywords": [ "adaptive euler-maruyama scheme", "mckean sdes", "mean-field fitzhugh-nagumo model", "super-linear growth", "application" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
