Multiple solutions for a coupled Kirchhoff system with fractional p-Laplacian and sign-changing weight functions

In this paper, we investigate the multiplicity of solutions for Kirchhoff fractional p-Laplacian system in bounded domains: ∑ i = 1 k [ u i ] s , p p θ − 1 ( − Δ ) p s u j ( x ) = λ j f j ( x ) | u...
