Convergence of Euler-Maruyama Method for Stochastic Differential Equations Driven by α−stable Lévy Motion

In the literature, the Euler-Maruyama (EM) method for ap-proximation purposes of stochastic differential Equations (SDE) driven by α-stable Lévy motions is reported. Convergence in probability of that method was proven but it is surrounded by some ambiguities. To accomplish the but without ambiguities, this article has derived conver-gence in probability of numerical EM method based on diffusion given by semimartingales for SDEs driven by α-stable processes. Some exam-ples are provided, their numerical solution are obtained and theoretical results are reconfirmed. The adopted method could be applied to other subclasses of semimartingales.
