本文研究了一类带大小结构的多种群模型,利用有限差分逼近的方法,证明了差分方程的解序列收敛到原系统的弱解.最后,论证了差分方程的解关于初值的连续依赖性.

In this paper, we investigate a class of size-structured populations model. We prove that the sequence of solutions of difference equations converges to the weak solution of original model via the methof of finite difference approximation. We also show the continuous dependence of the solution of difference equations with respect to the initial condition.
