Abstract

In this paper, we study the following fourth-order elliptic equation with p-Laplacian, steep potential well and sublinear perturbation: \[\begin{cases} \Delta^2u-\kappa\Delta_p u+\mu V(x)u=f(x, u)+ \xi(x) \vert u\vert^{q-2}u, \quad &x\in \Omega,\\ u= \Delta u=0, \quad &\text{on }\partial\Omega, \end{cases}\] where \(N \geq 5\), \(\Omega\) is a bounded domain in \(\mathbb{R}^N\) with smooth boundary \(\partial\Omega\), \(\Delta^2:=\Delta(\Delta)\) is the biharmonic operator, \(\Delta_p u= \operatorname{div}\left(\vert \nabla u\vert^{p-2} \nabla u\right)\) with \(p>2\), \(\mu,\kappa>0\) are parameters, \(f \in \mathcal{C}\left(\Omega \times \mathbb{R}, \mathbb{R}\right)\), \(\xi\in L^{\frac{2}{2-q}}\left(\Omega\right)\) with \(1\leq q<2\), we have the potential \(V\in \mathcal{C}(\Omega,\mathbb{R})\). Using variational methods, we establish the existence of infinitely many nontrivial high energy solutions under certain assumptions on \(V\) and \(f\).
