Abstract.
Given an arbitrary relatively compact (finely) open subset of \({\mathbb R}^d, \mu\)-eigenvalues of \(-A(D)+\nu\) are studied where \(A(D)\) is the Dirichlet Laplacian on D and \(\mu,\nu\) are measures on \({\mathbb R}^d\) such that \(G_X^\mu\) is continuous and \(G_X^\nu\) is bounded for every ball X in \({\mathbb R}^d (G_X\) being Green's function for X). Moreover, it is shown that these eigenvalues depend continuously on D and \(\nu\). The results are based on very general compactness and convergence properties of integral operators of Kato type which are developed before.
