The existence of periodic solutions of a neutral integro-differential equation with infinite delay was studied. 摘要本文考慮具無(wú)窮時(shí)滯中立型積分微分方程周期解的存在性。
We discuss the stability of a kind of neutral delayed linear differential equation, and obtain the stability criterion of this equation. 摘要討論了一類(lèi)中立型線(xiàn)性微分方程的穩定性，得到其零點(diǎn)穩定的充分判別準則。
