摘要
本文获得了时滞Logistic方程 x'(t)=r(t)x(t)[1-a_1x(g_1(t))-a_2x(g_2(t))]~a,t≥0关于其正平衡状态x=1/(a_1+a_2)存在非振动解的充分条件与充要条件,改进并推广了Aiello中的结果.
In this paper some sufficient, as well as necessary and sufficient conditions for the existence of nonoscillatory solutions about the positive stationary state - x =1/(α1+α2) of the delay logistic equationx'(t) =r(t)x(t)[l-α1x(g1(t) -α2x(g2(t)],t≥0 are obtained, which improve and generalize the results in Aiello [4].
