Abstract
In this paper, we consider the existence of homoclinic solution for a class of damped vibration problem
For every \(k\in {\mathbb {N}}\), we obtain the 2kT-periodic solution \(x_{k}\) by a standard minimizing argument. By taking the limit of \(\{x_{k}\}\), we get a solution \(x_{0}\) of this problem. We prove that \(x_{0}\) satisfies \(x_{0}\rightarrow 0\) and \({\dot{x}}_{0}\rightarrow 0\) as \(t\rightarrow \pm \infty \), and therefore \(x_{0}\) is a homoclinic solution of the problem.
