摘要
本文给出保证平方Logistic方程N′(t)=r(t)N(t)(l-bN(t-τ)-cN2(t-τ))的每一正解N(t)趋于正平衡点N*的一组充分条件.改进了 Gapalsamy,Ladas和罗交晚等人的结果.
In this paper, the author gives different sufficient conditions that guarantee ev- ery positive solution of the equation N'(t) =r(t)N(t)(l-bN(t-τ)-cN2(t-τ)) to tend to the positive equilibrium N* , some results obtained by Gapasarny, Ladas and Luo are improved.
