Abstract:

In this paper, we are concerned with the boundedness of all the solutions and the existence of quasi-periodic solutions for second order differential equations

\begin{displaymath}x^{\prime\prime} + g(x) = e(t), \end{displaymath}

where the 1-periodic function $e(t)$ is a smooth function and $g(x)$satisfies sublinearity:

\begin{displaymath}{sign}(x)\cdot g(x)\to+\infty,\quad g(x)/x\to 0 \quad {as}\,\,\, \vert x\vert\to+\infty. \end{displaymath}
