We construct an Ahlfors-Bers complex analytic model for the Teichmuller space of the universal hyperbolic lamination (also known as Sullivans Teichmuller space) and the renormalized Weil-Petersson metric on it as an extension of the usual one. In this setting, we prove that Sullivans Teichmuller space is Kahler isometric biholomorphic to the space of continuous functions from the profinite completion of the fundamental group of a compact Riemann surface of genus greater than or equal to two to the Teichmuller space of this surface; i.e. We find natural Kahler coordinates for the Sullivans Teichmuller space. This is the main result. As a corollary, we show the expected fact that the Nag-Verjovsky embedding is transversal to the Sullivans Teichmuller space contained in the universal one.
We introduce a function model for the Teichmuller space of a closed hyperbolic Riemann surface. Then we introduce a new metric by using the maximum norm on the function space on the Teichmuller space. We prove that the identity map from the Teichmull
In a paper of Cui and Zinsmeister the equivalence among three definitions of BMO-Teichmuller spaces associated with a Fuchsian group was proven using the Douady-Earle extension operator. In this paper, we show that these equivalences are actually bih
We introduce the concept of a new kind of symmetric homeomorphisms on the unit circle, which is derived from the generalization of symmetric homeomorphisms on the real line. By the investigation of the barycentric extension for this class of circle h
Teichmullers problem from 1944 is this: Given $xin [0,1)$ find and describe the extremal quasiconformal map $f:IDtoID$, $f|partial ID=identity$ and $f(0)=-xleq 0$. We consider this problem in the setting of minimisers of $L^p$-mean distortion. The cl
We introduce $Theta$-positivity, a new notion of positivity in real semisimple Lie groups. The notion of $Theta$-positivity generalizes at the same time Lusztigs total positivity in split real Lie groups as well as well known concepts of positivity i
