On the asymptotic behavior of the eigenvalues of nonlinear elliptic problems in domains becoming unbounded

We analyze the asymptotic behavior of eigenvalues nonlinear elliptic problems under Dirichlet boundary conditions and mixed (Dirichlet, Neumann) on domains becoming unbounded. make intensive use Picone identity to overcome nonlinearity complications. Altogether makes proof easier with respect known in linear case. Surprisingly critically differs from case pure for some class problems.
