Resumen de On existence of periodic solution to certain nonlinear third order differential equations
In this paper, it is investigated the existence of periodic solutions to the nonlinear third order differential equation :x'" + c2(t)x" + c1(f)x' + f(t, x) = p(t, x, x', x").The Leray-Schauder principle is used to show the existence of periodic solutions of this equation.
