On the asymptotic behavior of solutions of certain third-order nonlinear differential equations (Q2387493)

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 \(t\to\infty\).
