Abstract:

In a recent paper with Aldo Pratelli we proved that any increasing functional of the first $k$ eigenvalues of the Dirichlet Laplacian admits a (quasi-)open minimizer among the subsets of $\mathbb{R}^N$ of unit measure. In this paper it is shown that every minimizer is uniformly bounded by a constant depending only on $k,N$.
