摘要
利用重合度理论中的延拓定理和不等式分析技巧,获得了一类具有多个偏差变元的Lienard型p-Lapla-cian泛函微分方程的周期解存在性的新的充分条件,推广和改进了已有文献的相关结果.
By using a continuation theory based on coincidence degree theory and inequality technique, some new sufficient conditions of periodic solutions are established for Lienard type P - Laplacian neutral functional differential equation with multiple deviating arguments. The results have extended and improved the related reports in the literatures.
