Abstract
We consider the linear eigenvalue problem -Delta u = lambda V(x)u, u is an element of D-0(1,2)(Omega), and its nonlinear generalization -Delta(p)u = lambda V(x)u(p-2)u, u is an element of D-0(1,p)(Omega). The set Omega need not be bounded, in particular, Omega = R-N is admitted. The weight function V may change sign and may have singular points. We show that there exists a sequence df eigenvalues lambda(n) --> infinity.
