Existence and uniqueness of periodic solutions for Rayleigh type p-Laplacian equation

In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of T-periodic solutions for the Rayleigh type p-Laplacian equation of the form (φp(x′(t)))′+f(t,x′(t))+g(t,x(t))=e(t).
