Abstract

In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of $T$-periodic solutions for a kind of Rayleigh equation with a deviating argument of the form $$ x''+f(x'(t)) +g(t,x(t-\tau(t)))=p(t). $$

Keywords: Rayleigh equation, deviating argument, periodic solution, coincidence degree
