GSTW02 - Geometry of eigenvalues

The symmetrized Asymptotic Mean Value (AMV) Laplacians extend the Laplace operator from Rn to metric measure spaces through appropriate averaging integrals. On complete Riemannian manifolds, they provide an alternative approximation of the Laplace—Beltrami operator. In this talk, I will present recent results obtained with Manuel Dias (VUB) about the spectral properties of these operators on compact doubling metric measure spaces. Our results notably apply to suitable unions of intersecting Riemannian manifolds.
