ASYMPTOTIC BOUNDEDNESS OF THE NUMERICAL SOLUTIONS OF STOCHASTIC AGE-DEPENDENT POPULATION SYSTEM

本文研究了一类具有年龄结构的随机种群系统的数值解问题.在线性增长条件下，利用Euler-Maruyama（EM）方法讨论了具有年龄结构的随机种群系统的数值解的p阶矩渐近有界性，并获得了渐近有界性准则.最后，通过数值算例对所得的结论进行了验证.
A class of stochastic age-dependent population system is studied in this paper. Under linear growth condition, we discuss the p-th asymptotic boundedness of the numerical solutions for stochastic age-dependent population system and establish a criterion for the asymptotical boundedness by using Euler-Maruyama (EM) method. Finally, numerical example is presented to demonstrate the accuracy of the conclusion
