| Abstract | In this paper we study the multiplicity of nontrivial solutions for nonlinear wave equation of the form${ u_{tt} − u_{xx} = b[(u + 1)^+ − 1] }$ in ${ (c, d) × \mathbb{R} }$ with Dirichlet boundary condition on the interval ${ c < x < d }$. We find the multiple nontrivial solutions of the equation. Here we reduce this problem into a two-dimensional problem by using variational reduction method and apply the Mountain Pass theorem to find the nontrivial solutions |
