摘要
考虑偶数阶非线性中立型微分方程,利用Lebesgue控制收敛定理获得了最终有界正解存在的一个充分必要条件.
In this paper we consider the existence for eventually positive solutions of evenorder nonlinear neutral differential equations, We use the Lebesgue's dominated convergence theorem to obtain new necessary and sufficient condition for the existence of eventually bounded positive solutions.
