Three solutions for a Neumann-type differential inclusion problem involving the p(x)-Laplacian
In this paper we consider Neumann-type differential inclusion problems involving the p ( x ) -Laplacian of the type { − div ( | ∇ u | p ( x ) − 2 ∇ u ) + | u | p ( x ) − 2 u ∈ λ ∂ F ( x , u ) in Ω , ∂ u ∂ γ = 0 on ∂ Ω . Applying a version of the non-smooth three-critical-points theorem we obtain...
