)∈C1(ℝ3xℝxℝ,ℝ),V(x)为变号函数,Fu=∂F/∂u,Fv=∂F/∂v。在满足一定条件下,利用Fountain定理证明了该问题存在无穷多高能量解。
Abstract:
This paper focus on the following forth-order elliptic equations involving non-local terms and
sign-changing potential
Where Δ2=Δ(Δ) is the biharmonic operator, V(x)∈C( ℝ3,ℝ), F(x,u,v )∈C1(ℝ3xℝxℝ,ℝ). V(x) is sign-changing function, Fu=∂F/∂u, Fv=∂F/∂v. Under certain conditions, it’s proved that there are infinitely many high-energy solutions to the problem using Fountain Theorem.
