Title: The Ihara/OdaMatsumoto Conjecture (I/OM)
Abstract: Ihara asked in the 1980's and OdaMatsumoto conjectured in 1996 that there should be a purely topologicalcombinatorial description of Aut(K), where K is the algebraic closure of the field of rational numbers. I/OM grew out of Grothendieck's famous "Dessins d'enfants" and ideas by Deligne, Ihara, Drinfel'd... In the talk I will review/explain the question and present the state of the art, in particular recent refinements of I/OM, based on the so called Bogomolov (birational anabelian) Program.
