Auxiliary principle for generalized strongly nonlinear mixed variational-like inequalities.
Let X and Y be complex Banach spaces of dimension greater than 2. We show that every 2-local Lie isomorphism ϕ of B(X) onto B(Y) has the form ϕ = φ + τ, where φ is an isomorphism or the negative of an anti-isomorphism of B(X) onto B(Y), and τ is a homogeneous map from B(X) into ℂI vanishing on all finite sums of commutators.
We study the existence of positive solutions of the quasilinear problem ⎧ , , ⎨ ⎩ u(x) > 0, , where is the N-Laplacian operator, is a continuous potential, is a continuous function. The main result follows from an iterative method based on Mountain Pass techniques.
