It is known that every finitely unbranched holomorphic covering π:S→S of a compact Riemann surface S with genus g≥2 induces an isometric embedding Φπ:Teich(S)→Teich(S).By the mutual relations between Strebel ray...

The eventually distance minimizing ray(EDM ray) in moduli spaces of the Riemann surfaces of analytic finite type with 3 g + n-3 〉 0 is studied, which was introduced by Farb and Masur [5]. The asymptotic distance o...

Abstract The non-uniqueness on geodesics and geodesic disks in the universal asymptotic Teichmfiller space AT(D) are studied in this paper. It is proved that if # is asymptotically extremal in [[#]] with h (μ) ...

The geometry of Teichmuller metric in an asymptotic Teichmuller space is studled in this article. First, a binary infinitesimal form of Teichmuller metric on AT(X) is proved. Then, the notion of angles between two g...

The purpose of this paper is to give a relatively elementary and direct proof of the Delta Inequality, which plays a very important role in the study of the extremal problem of quasiconformal mappings.
