摘要
研究了具有年龄结构的n种群竞争系统的最优收获问题,利用压缩不动点原理证明该系统的解是存在唯一的,并且得到最优控制所满足的必要条件。
optimal harvesting policy for an age-dependent n-dimension competing species is concerned. The existence and uniqueness of nonnegative solution of the system are proved using the fixed point theorem and the existence and uniqueness Of an optimal Control are given.
