Abstract
In this paper we mainly consider the stability of numerical solution for the differential equation with piecewise constant arguments of mixed type By the technique of solving differential equations the concrete form of analytic solution is derived Furthermore the conditions under which the analytic solution is asymptotically stable are obtained Then the RungeKutta methods are applied to the equation using the theory of characteristic the conditions under which the numerical solution is asymptotically stable are presented Moreover the necessary and sufficient conditions under which the numerical stability regions contain the analytical stability regions are determined In particular for theta methods we give the corresponding results of stability which are the generalization of conclusions in the existed paper Finally some numerical experiments are being included to support the theoretical resultsI would like to express my gratitude to the referees for their careful reading and for pointing out some errors in previous version of the paper The author is very grateful to Professors Mingzhu Liu Minghui Song and Zhanwen Yang for their helpful comments and constructive suggestions
