Boundedness of solutions to a retarded Liénard equation

This paper is concerned with the following retarded Li\'{e}nard equation $$x''(t)+f_1(x(t))(x'(t))^2+f_2(x(t))x'(t)+g_1(x(t))+g_2(x(t-\tau(t)))=e(t).$$ We prove a new theorem which ensures that all solutions of the above Li\'{e}nard equation satisfying given initial c...
