一类时滞微分方程的全局吸引性

Global Attractivity in a Class of Delay Difference Equation

考虑时滞微分方程 :dN(t)dt =r(t)N(t) [1 -N( g(t) )k ]α,t≥ 0 .其中α≥ 1是两个正奇数之比 。

Consider the delay difference equation:dN(t)dt=r(t)N(t)[1-N(g(t))k] α,t≥0.where α≥1 is the ratio of two positive odd integers,We obtain new sufficient conditions for the global attractivity of the equilibrium k of equation.
