Periodic solutions for pp-Laplacian neutral Rayleigh equation with a deviating argument

By using topological degree theory and some analytical skill, some criteria to guarantee the existence of ωω-periodic solutions are derived for pp-Laplacian neutral Rayleigh equation with a deviating argument of the following form (ϕp((x(t)−cx(t−σ))′))′+f(x′(t))+g(x(t−τ(t)))=e(t).(ϕp((x(t)−cx(t−σ))′))′+f(x′(t))+g(x(t−τ(t)))=e(t).
