چکیده

The singular chain complex of the little 2-cubes operad defines an operad in simplicial cocommutative coalgebras. This operad has a dual structure, formed by a cooperad in cosimplicial commutative algebras, which defines model of the prounipotent completion of the topological operad of little

OPERADS & GROTHENDIECK - TEICHMÜLLER GROUPS – DRAFT DOCUMENT by

This preprint is an extract from a research monograph in preparation on the homotopy of operads and Grothendieck-Teichmüller groups. The ultimate objective of this book is to prove that the Grothendieck-Teichmüller group is the group of homotopy automorphisms of a rational completion of the little 2-discs operad. The present excerpts include a comprehensive account of the fundamental concepts o...

Characters of the Grothendieck-teichmüller Group through Rigidity of the Burau Representation

We present examples of characters of absolute Galois groups of number fields that can be recovered through their action by automorphisms on the profinite completion of the braid groups, using a “rigidity” approach. The way we use to recover them is through classical representations of the braid groups, and in particular through the Burau representation. This enables one to extend these characte...

The Grothendieck Program

The definition of the Grothendieck-Teichmüller group by Drinfeld was motivated by applications to quantum group theory and by Grothendieck’s program aiming to understand a geometric counterpart of absolute Galois groups. The purpose of the this outlook chapter is to give an overview of this program, and to survey the connections between the structures occurring in our study of the homotopy of o...

Action of the Grothendieck-Teichmüller group on torsion elements of full Teichmüller modular groups in genus zero

In this paper we establish the action of the Grothendieck-Teichmüller group ĜT on the prime order torsion elements of the profinite fundamental group π 1 (M0,[n]). As an intermediate result, we prove that the conjugacy classes of prime order torsion of π̂1(M0,[n]) are exactly the discrete prime order ones of the π1(M0,[n]).
