Abstract

The paper deals with convergence and stability of the semiimplicit Euler method with variable stepsize for a linear stochastic pantograph differential equation(SPDE). It is proved that the semi-implicit Euler method with variable stepsize is convergent with strong order p = 1/2. The conditions under which the method is mean square stability are determined and the numerical experiments are given.
