研究一类基于时滞和年龄分布的非线性种群系统,其状态方程由一阶偏泛函微分方程描述.利用不动点定理得到了系统解的存在唯一性.
A class of nonlinear population systems with time delay and age distribution is studied,whose state system is described by a partial functional differential equation.The uniqueness of solution for the system is proved by means of fixed point theorem.
