Abstract:Existence of periodic solutions for the Rayleigh type p-Laplacian equation with a deviating argument(φp(x (t))) +f(t,x (t))+g(t,x(t-τ(t)))=e(t)is studied.By using topological degree theory and a priori estimate,some new results are obtained.Our work generalizes and improves the known results in the literature.
Keywords:p-Laplacian equation  periodic solution  priori estimate
