Abstract:

In this paper, we consider the following quasi-linear elliptic exterior problem with Neumann boundary value conditions 

where Ω is a smooth exterior domain of the Euclidean space(RN,|·|)(N ≥ 3), and n is the unit vector of the outward normal on the boundary ∂Ω. λ is a positive parameter, 1< p< N, 1< q< p< r< p*, p*=Np/(N-p). By the mountain-pass theorem and Ekeland's variational principle, we establish the existence of two solutions for this problem when functions a(x), b(x), h1(x), h2(x) and g(x) satisfy certain conditions.

Key words: Mountain-pass Theorem, Variational methods, Neumann boundary conditions
