چکیده

Let T (S) be the Teichmüller space of an oriented surface S of finite type. We discuss the action of subgroups of the mapping class group of S on the CAT(0)-boundary of the completion of T (S) with respect to the Weil-Petersson metric. We show that the set of invariant Borel probability measures for the Weil-Petersson flow on moduli space which are supported on a closed orbit is dense in the space of all ergodic invariant probability measures.

The Weil-petersson Geodesic Flow Is Ergodic

We prove that the geodesic flow for the Weil-Petersson metric on the moduli space of Riemann surfaces is ergodic (and in fact Bernoulli) and has finite, positive metric entropy.

A Weil-petersson Type Metric on Spaces of Metric Graphs

Given a compact topological surface V with negative Euler characteristic, the Teichmüller space Teich(V ) describes the marked Riemann metrics (with constant curvature κ = −1) which it supports. More precisely, Teich(V ) is the set of equivalence classes (Vg, φ), where Vg is a hyperbolic surface with Riemann metric g and φ : V → Vg is a homeomorphism, with (Vg1 , φ1) equivalent to (Vg2 , φ2) if...

On the Weil-petersson Curvature of the Moduli Space of Riemann Surfaces of Large Genus

Let Sg be a closed surface of genus g and Mg be the moduli space of Sg endowed with the Weil-Petersson metric. In this paper we investigate the Weil-Petersson curvatures of Mg for large genus g. First, we study the asymptotic behavior of the extremal Weil-Petersson holomorphic sectional curvatures at certain thick surfaces in Mg as g → ∞. Then we prove two curvature properties on the whole spac...

On the Weil-petersson Volume and the First Chern Class of the Moduli Space of Calabi-yau Manifolds

In this paper, we continue our study of the Weil-Petersson geometry as in the previous paper [10], in which we have proved the boundedness of the Weil-Petersson volume, among the other results. The main results of this paper are that the volume and the integrations of Ricci curvature of the Weil-Petersson metric on the moduli space are rational numbers. In particular, the Ricci curvature define...
