The universal Ptolemy-Teichmuller groupoid We define the universal Ptolemy-Teichmuller groupoid, a generalization of Penner's universal Ptolemy groupoid, on which the Grothendieck-Teichmuller group - and thus also the absolute Galois group - acts naturally as auto- morphism group...

那里也曾有过一个小型工作讨论班,Ladegaillerie在上面给了几次关于William Thurston在Teichmuller空间上的工作的报告,这激起了格洛腾迪克在这个学科的兴趣。到1980年代,格洛腾迪克觉得他已经做了他所能做的事来试着激发蒙彼利尔这些不那么热心的学生,于是决定去申请科学研究国家中心(CNRS)的研究员职位。CNRS是一个法国...

Galois-Teichmuller Theory and Arithmetic Geometry From the 1980's, Grothendieck's "Esquisse d'un Programme" triggered tremendous developments in number theory and arithmetic geometry, extending from the studies of anabelian geometry and related Galois representations to those of polylog... 中村, 博昭,...
We study actions of the Grothendieck-Teichmuller group GRT on Poisson cohomologies of Poisson manifolds, and prove some "go" and "no-go" theorems associated with these actions.Alm, JohanMerkulov, SergeiJournal of noncommutative geometryJ. Alm and S. Merkulov. Grothendieck-Teichmu¨ller group and...
A cohomological interpretation of the Grothendieck-Teichmuller groups (eng) Let P n be the pure braid group of the 2-sphere, with n strings ( n ≥ 3), and \\( \\hat P_n \\) be its pro- ℓ completion ( ℓ : a fixed prime number). We shall study what we call the special...
We present a formalism within which the relationship (discovered by Drinfel'd in [Dr1], [Dr2]) between associators (for quasi-triangular quasi-Hopf algebras) and (a variant of) the Grothendieck-Teichmuller group becomes simple and natural, leading to a simplification of Drinfel'd's original ...
