چکیده
This paper is a brief account of the moduli of complex curves from the perspective of noncommutative geometry. Using a uniformization of Riemann surfaces by the ordered abelian groups, we prove that modulo the Torelli group, the mapping class group of surface of genus g with n holes, is linear arithmetic group of rank 6g − 6 + 2n.

Moduli of complex curves and noncommutative geometry I: Riemann surfaces and dimension groups
This paper is a brief account of the moduli of complex curves from the perspective of noncommutative geometry. We focus on the uniformization of Riemann surfaces by the ordered K-groups of a noncommutative C-algebra. Using this approach, we prove “generic” arithmeticity of the mapping class group and study correspondences between complex and noncommutative tori.
متن کاملModuli of complex curves and noncommutative geometry I: classification of complex and quantum tori
This paper is a brief account of the moduli of complex curves from the perspective of noncommutative geometry. We focus on problems of Riemann surface theory, which can be settled using K-groups of a noncommutative C∗-algebra. On this way, we prove “generic” arithmeticity of the mapping class group and study correspondences between complex and noncommutative tori.
متن کاملOn complex and noncommutative tori
The “noncommutative geometry” of complex algebraic curves is studied. As first step, we clarify a morphism between elliptic curves, or complex tori, and C-algebras Tθ = {u, v | vu = e2πiθuv}, or noncommutative tori. The main result says that under the morphism isomorphic elliptic curves map to the Morita equivalent noncommutative tori. Our approach is based on the rigidity of the length spectra...
متن کاملNoncommutative Geometry and Compactifications of the Moduli Space of Curves
In this paper we show that the homology of a certain natural compactification of the moduli space, introduced by Kontsevich in his study of Witten’s conjectures, can be described completely algebraically as the homology of a certain differential graded Lie algebra. This two-parameter family is constructed by using a Lie cobracket on the space of noncommutative 0-forms, a structure which corresp...
متن کاملTeichmüller spaces, triangle groups and Grothendieck dessins
This survey article considers moduli of algebraic curves using techniques from the complex analytic Teichmüller theory of deformations for the underlying Riemann surfaces and combinatorial topology of surfaces. The aim is to provide a readable narrative, suitable for people with a little background in complex analysis, hyperbolic plane geometry and discrete groups, who wish to understand the in...
