Metodi di punto critico per equazioni nonlineari ellittiche di segno indefinito e sistemi Hamiltoniani
A Dirichlet problem with asymptotically linear and changing sign nonlinearity.
This paper deals with the problem of finding positive solutions to the equation -∆[u] = g(x,u) on a bounded domain 'Omega' with Dirichlet boundary conditions. The function g can change sign and has asymptotically linear behaviour. The solutions are found using the Mountain Pass Theorem.
