摘要
本文对一类非线性人口发展方程提出了Mild解和Weak解的概念,并讨论了二者之间的关系。
This paper is a study of the solution of nonlinear age dependent population evo-lution equation. A more resonable definition of mild solution and weak solution of the equation is suggested, and their relationship is investigated in order to provide a more exact theoretical foundation for population analysis.
