Profinite Grothendieck-Teichmüller theory and completed curve complexes

Sep 1, 2022, 4:00 PM


Pierre Lochak (Paris Jussieu)


After surveying the early developments in profinite
Grothendieck-Teichmüller theory, I will explain how the introduction of
completed curve complexes (as well as other types of complexes) led to
some more recent results, including an important rigidity property which
enables one to define the profinite version of associators.
