On the existence of periodic solutions for p-Laplacian generalized Liénard equation

By employing Mawhin's continuation theorem, the existence of periodic solutions of the p-Laplacian generalized Liénard equation with deviating argument(ϕp(x′(t)))′+f(t,x(t))x′(t)+β(t)g(x(t-τ(t)))=e(t)under various assumptions are obtained.
