Periodic solutions for fourth-order p-Laplacian functional differential equations with sign-variable coefficient
Using the theory of coincidence degree, we show the existence of periodic solutions to the fourth-order p-Laplacian differential equations of Lienard-type $$ \phi_p(x''))''+f(x(t))x'(t)+\alpha(t)g_1(x(t-\tau_1(t,x(t)))) +\beta(t)g_2(x(t-\tau_1(t,x(t))))=p(t). $$ The r...
