本文研究一类具偏差变元的二阶p-Laplacian方程(φp(y'(t)))’+f(y'(t))+g(y(y(t-τ(t)))=e(t)的周期解问题.利用Mawhin重合度拓展定理得到了周期解存在性的新的结果.
By employing the continuation theorem of coincidence degree principle developed by Mawhin, a kind of second order p-Laplacian differential equation with a deviating argument (φp(y'(t)))'+f(y'(t))+g(y(y(t-τ(t)))=e(t) is studied. Some new results on the existence of periodic solutions are obtained.
