摘要
本文讨论了一类非线性种群发展方程.证明了解的存在性和唯一性,利用临界增生率概念和算子的实特征值,得到了系统渐近稳定、稳定和不稳定的充分条件.
A class of nonlinear population equations is discussed.The existence and uniqueness of the solution are proved.By using the concept of critical proliferation rate and characteristic value of operator,the sufficient conditions of the asymptotic stability,stability and nonstability are obtained.
