摘要
本文利用单调逼近方法,研究带大小结构的捕食-被捕食系统的初边值问题,得到了系统解的存在唯一性,并且证明了序列是线性收敛的.
In this paper, a monotone approximation is developed for solving the initialboundary value problem of prey-predator system with size-structure. Such an approximation results in the existence and uniqueness of the solution for the system. Furthermore, a first order convergence is established.
