摘要：
This paper develops the partially truncated Euler-Maruyama method for a class of highly nonlinear pantograph stochastic differential equations under the generalized Khasminskiitype conditions. The order of L-P-convergence is obtained. Moreover, some almost sure polynomial stability and mean square polynomial stability criteria are established for the numerical solution. Numerical examples are provided to illustrate the theoretical results. (C) 2018 Elsevier Inc. All rights reserved.
