چکیده
In this paper, we establish some new sufficient conditions which guarantee the boundedness and the uniform boundedness of solutions of certain nonlinear and nonautonomous differential equations of second order. By defining appropriate Liapunov functions, we obtain some new results on the subject, and examples are also provided to illustrate the feasibility of the proposed results. By this work, we extend and improve some boundedness results in the literature.
