Dmitry Jakobson: Measures on spaces of Riemannian metrics

We construct Gaussian measure on the manifold of Riemannian metrics with the fixed volume form. We show that diameter and Laplace eigenvalue and volume entropy functionals are all integrable with respect to our measures. We also compute the characteristic function for the L2 (Ebin) distance from a random metric to the reference metric.
