一类时滞人口模型的全局吸引性

Global Attractivity for a Population Model with Delay

给出了保证时滞人口模型N＇(t)=r(t)N(t)1-N(t-τ)/1-λN (t-τ),t≥0的每一正解N(t)趋于正平衡点N*=1(t→∞)的一族充分条件,改进了相关文献中的一些结论.

A sufficient condition that guarantees every solution of the population model with delay was given N′(t)=r(t)N(t)1-N(t-τ)1-λN(t-τ),t≥0, to converge to the equilibrium N *=1 as t→∞. The results in related reference are improved.
