利用重合度理論研究了一類多偏差變元的p-Laplacian方程周期解存在性問題,獲得了其周期解存在性的新結(jié)論,推廣和改進(jìn)了已有文獻(xiàn)中的相關(guān)結(jié)論.

由于p-Laplacian方程具有較廣泛的應(yīng)用背景,因此一直受到人們極大的關(guān)注,也取得了許多很好的成果[1-10].但針對具有多偏差變元高階p-Laplacian方程周期解存在性研究則不多,最近文[5]、[6]和文[7]分別研究了具有兩個(gè)偏差變元方程

By using the theorem of coincidence degree,existence of periodic solutions for a kind of p-Laplacian equation with deviating arguments is studied.Some new results for the existence of periodic solutions are obtained,which extend and improve the related reports in the literatures.
