Multiple solutions for two nonlinear problems involving the $$p$$-Laplacian. (English) Zbl 1224.35152
Summary: Using variational arguments we prove the existence of at least two solutions for two elliptic problems involving the $$p$$-Laplacian. Dirichlet and Neumann boundary conditions will be considered in the two problems where a positive parameter appears.
