具有偏差变元的四阶p-Laplacian方程周期解的存在性

Existence of Periodic Solutions for Four-Order p-Laplacian Equation with Deviating Argument

应用重合度理论和一些分析技巧,研究了一类四阶p-Laplacian中立型微分方程,获得其周期解存在性新的充分条件,推广和改进了已有文献中的相关结论.

By application of coincidence degree theory and some analysis skills,we consider a p-Lapla?cian Rayleigh neutral differential equation with variable parameters.Some new sufficient conditions for the ex?istence of periodic solutions are obtained.The results have extended and improved the related reports in the literatures.
