This paper is motivated by the maximization of k-th eigenvalue Laplace operator with Neumann boundary conditions among domains $${{\mathbb {R}}}^N$$ prescribed measure. We relax problem to class (possibly degenerate) densities in $$\mathbb {R}^N$$ mass and prove existence an optimal density. For $$k=1,2$$ , two problems are equivalent maximizers known be one equal balls, respectively. $$k \ge 3...
