A Commentary on Teichmüller's paper "Über Extremalprobleme der konformen Geometrie" (On extremal problems in conformal geometry)

Norbert A'Campo, Athanase Papadopoulos

We comment on the paper Über Extremalprobleme der konformen Geometrie (On extremal problems in conformal geometry) by Teichmüller, published in 1941. This paper contains ideas on a…

Actions of the Absolute Galois Group

Norbert A'Campo, Lizhen Ji, Athanase Papadopoulos

We review some ideas of Grothendieck and others on actions of the absolute Galois group Γ Q of Q (the automorphism group of the tower of finite extensions of Q), related to the geo…

On Grothendieck's tame topology

Norbert A'Campo, Lizhen Ji, Athanase Papadopoulos

Grothendieck's Esquisse d'un programme is often referred to for the ideas it contains on dessins d'enfants, the Teichm{ü}ller tower, and the actions of the absolute Galois group on…

On Grothendieck's construction of Teichmüller space

Norbert A'Campo, Lizhen Ji, Athanase Papadopoulos

In his 1944 paper Veränderliche Riemannsche Flächen , Teichmüller defined a structure of complex manifold on the set of isomorphism classes of marked closed Riemann surfaces of gen…

On the early history of moduli and Teichm{ü}ller spaces

Norbert A'Campo, Lizhen Ji, Athanase Papadopoulos

We survey some major contributions to Riemann's moduli space and Teichm{ü}ller space. Our report has a historical character, but the stress is on the chain of mathematical ideas. W…
