与年龄相关的随机种群模型解的均方散逸性

讨论了一类与年龄相关的随机种群模型数值解的均方散逸性: 基于步长~$h$~受限制和无限制的两种条件, 利用倒向欧拉法和补偿的倒向欧拉法分析了该随机种群模型数值解的均方散逸性并加以证明, 最后得出补偿的倒向欧拉法更适合解决与年龄相关的随机种群模型数值解的均方散逸性问题.

Mean-square dissipativity of two numerical methods for stochastic age-dependent population equations with jumps

The mean-square dissipativity of the numerical solution for a class of stochastic age-dependent population equations with jumps is discussed. Based on the step length under the condition of limited and unlimited, it is essential for studying the mean-square dissipativity to use backward Euler method and compensated backward Euler method for stochastic age-dependent population equations with jumps. The results show that the compensated backward Euler method is more suitable for solving the mean-square dissipativity about stochastic age-dependent population equations with jumps.
