✦ Synopsis

In the literature [1] [Existence and uniqueness of the solutions and convergence of semiimplicit Euler methods for stochastic pantograph equation, J. Math. Anal. Appl. 325 (2007Appl. 325 ( ) 1142Appl. 325 ( -1159]], Fan and Liu investigated the existence and uniqueness of the solution for stochastic pantograph equation and proved the convergence of the semi-implicit Euler methods under the Lipschitz condition and the linear growth condition. Unfortunately, the main result of convergence derived by the conditions is somewhat restrictive for the purpose of practical application, because there are many stochastic pantograph equations that only satisfy the local Lipschitz condition. In this note we improve the corresponding results in the above-mentioned reference.

In this paper, we study the following stochastic equations with variable delays and random jump magnitudes: We establish the semi-implicit Euler approximate solutions for the above systems and prove that the approximate solutions converge to the analytical solutions in the meansquare sense as well

We are concerned with estimating parameter values at which bifurcations occur in stochastic delay differential equations. After a brief review of bifurcation, we employ a numerical approach and consider how bifurcation values are influenced by the choice of numerical scheme and the step length and b
