چکیده

In this article we prove that for any hyperbolic Riemann surface M of infinite analytic type, the little Bers space Q0(M) is isomorphic to c0. As a consequence of this result, if M is such a Riemann surface, then its asymptotic Teichmüller space AT (M) is bi-Lipschitz equivalent to a bounded open subset of the Banach space l∞/c0. Further, if M and N are two such Riemann surfaces, their asymptotic Teichmüller spaces, AT (M) and AT (N), are locally bi-Lipschitz equivalent.

On Asymptotic Weil-Petersson Geometry of Teichmüller Space of Riemann Surfaces

We investigate the asymptotic behavior of curvatures of the Weil-Petersson metric in Teichmüller space. We use a pointwise curvature estimate to study directions, in the tangent space, of extremely negative curvature and directions of asymptotically zero curvatures.

Asymptotic Flatness of the Weil–Petersson Metric on Teichmüller Space

In this paper, we show that there is no negative upper bound for the sectional curvature of Teichmüller space of Riemann surfaces with the Weil–Petersson metric. Mathematics Subject Classifications (2000). 32G15, 53C21, 30F60.

Statistical Hyperbolicity in Teichmüller Space

In this paper we explore the idea that Teichmüller space with the Teichmüller metric is hyperbolic “on average.” We consider several different measures on Teichmüller space and show that with respect to each one, the average distance between points in a ball of radius r is asymptotic to 2r, which is as large as possible.

Characterization of the Asymptotic Teichmüller Space of the Open Unit Disk through Shears

We give a parametrization of the asymptotic Teichmüller space AT (D) of the open unit disk through a space of equivalent classes of the shear functions induced by quasisymmetric homeomorphisms on the Farey tesselation of the disk. Then using the parametrization, we define a metric on AT (D). Two other related metrics are also introduced on AT (D) by using cross-ratio distortions or quadrilatera...

On Behavior of Pairs of Teichmüller Geodesic Rays

In this paper, we obtain the explicit limit value of the Teichmüller distance between two Teichmüller geodesic rays which are determined by Jenkins-Strebel differentials having a common end point in the augmented Teichmüller space. Furthermore, we also obtain a condition under which these two rays are asymptotic. This is similar to a result of Farb and Masur.
