（>>378 より）Fierce Inertia says:が引用している Jannsen-Wingberg theorem って
下記のAbsolute Galois group wikipediaで、Examples２番目のLet K be a finite extension云々で、
This is a result of Uwe Jannsen and Kay Wingberg.[5][6] だと思う
で、そのすぐ下のProblems
”No direct description is known for the absolute Galois group of the rational numbers. In this case, it follows from Belyi's theorem that the absolute Galois group has a faithful action on the dessins d'enfants of Grothendieck (maps on surfaces), enabling us to "see" the Galois theory of algebraic number fields.”
が、遠アーベルに繋がる話で
実際、次の”Dessin d'enfant”wikipediaの”Dessins d'enfant in their modern form were then rediscovered over a century later and named by Alexander Grothendieck in 1984 in his Esquisse d'un Programme.[3]”
で、これが遠アーベルじゃね（＾＾；
