Abstract
This work aims to develop an explicit approximation scheme for solving stochastic differential systems based on the Euler–Maruyama scheme. We demonstrate the strong consistency and convergence properties of the proposed scheme. In addition, in a mean-square sense, we perform linear and nonlinear asymptotic stability analysis for the multiplicative and additive cases. At the end of the paper, several numerical examples arising in biology, neurology, and population dynamics are carried out to illustrate the obtained convergence and stability properties.
