✦ Synopsis


Let 0 R N be any open set. We study the nonlinear eigenvalue problem &2 p u =*V(x) |u| p&2 u, u # D 1, p 0 (0), where 1<p<N and V # L 1 loc (0) may have strong singularities and an indefinite sign. The key ingredient is a precised concentrationcompactness lemma related to V-dependent limiting problems. This work follows, extends, and simplifies that of A. Tertikas (1998, J. Funct. Anal. 154, 42 66) dealing with the positive linear case for 0=R N .

This paper considers the problem of finding the zeros of an operator G on a Hilbert space subject to a constraint of the general form P(x) = x. Convergence theorems are given for a class of iterative methods and, using these results, we derive several techniques for solving eigenvalue problems, one
