Positive solutions for Neumann elliptic problems involving critical Hardy–Sobolev exponent with boundary singularities Original Research Article

In this paper we consider the existence of positive solution for some semilinear elliptic equations with Neumann boundary condition involving a critical Hardy–Sobolev exponent and Hardy terms with boundary singularities. Using mountain pass lemma without (PS) condition and the strong maximum principle, we get the existence of a positive solution.
