摘要 利用重合度理论,研究一类具有奇性的Laplacian型方程,获得其周期正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 using the continuation theorem of coincidence degree, we study a Laplacian-like equation with a singularity. Some new sufficient conditions for the existence of positive periodic solutions are obtained.The results have extended and improved the related reports in the literatures.
