一类含间隙分布时滞的种群模型稳定性研究
Study of stabillty of a type of gap-distributed delay of population models
【摘要】 主要借助螺线特性 ,对一类含间隙分布时滞的种群增长模型特征方程λ +c=d( 1 +λT) -n- 1 e-αλT 的稳定性随T变化而改变的情况作了比较完整的分析讨论 ,并把文献 [3]中主要结论的错误性予以更正和完善 .
【Abstract】 A type of the characteristic equation of a population model with gap?distribution delay is studied.The variational situation of stability with the change of delay has been investigated and completely by means of the character of spiral.The wrong conclusion of referrence[3] has been correced.
