HU Jian-cheng

Open publisher page 1 citations

Abstract

Based on the well-established numerical methods for the deterministic ordinary differential equations the Euler method is applied to a scalar autonomous stochastic ordinary differential equation and three Euler numerical schemes are given: explicit scheme;semi-implicit sheme and implicit scheme.One type of stability of the Euler method,T-stability,is considered.Numerical results of a linear test equation show that the Euler method for solving SODEs is meaningful.
