Abstract:
In this paper, we study the existence of periodic solutions for a fourth-order p-Laplacian differential equation with a deviating argument as follows:
[φp(u″(t))]″+f(u″(t))+g(u(t−τ(t)))=e(t).
Under various assumptions, the existence of periodic solutions of the problem is obtained by applying Mawhin’s continuation theorem.
