Abstract: I will describe how, in the nonlinear setting of CD(K,infty) spaces, the stability of the Krasnoselskii spectrum of the Laplace operator -Delta holds under measured Gromov-Hausdorff convergence. Additionally, every element lambda in the Krasnoselskii spectrum has indeed an eigenvalue, namely there exists a nontrivial u satisfying the (nonlinear) eigenvalue equation - Delta u = lambda u.
