论文摘要
本文研究了具有非线性密度依赖性死亡率的Nicholson-type微分方程的$ω$周期系统。使用学位理论,我们获得了足够的条件,以实现阳性溶液$ω$周期的存在。我们的结果补充了先前关于该主题的研究。
This article studies an $ω$-periodic system of Nicholson-type differential equations with nonlinear density-dependent mortality rate. Using the degree theory we obtain sufficient conditions for the existence of a positive solution $ω$-periodic. Our result complement previous researches on the subject.
