On the asymptotic behavior of solutions of certain third-order nonlinear differential equations. (English) Zbl 1077.34052
Summary: We establish sufficient conditions under which all solutions of the third-order nonlinear differential equation $$\dddot x+\psi(x,\dot x, \ddot x)\ddot x+ f(x,\dot x)= p(t, x,\dot x,\ddot x)$$ are bounded and converge to zero as $$t\to\infty$$.
