2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/139231A theory of differential equations driven by a non-differentiable path has recently been developed by Lyons. We develop an alternative approach to this theory, using (modified Euler approximations), and investigate its applicability to stochastic differential equations driven by Brownian motion. We also give some other examples showing that the main results are reasonably sharp.ProbabilityClassical Analysis and ODEs60H10text
