Uniqueness of indecomposable idempotents in algebras with involution
Valentijn Karemaker, Akio Tamagawa, Chia-Fu Yu
We prove uniqueness of a decomposition of into indecomposable Hermitian idempotents in an order of a finite-dimensional -algebra with positive involution, by genera…
The -step solvable anabelian geometry of number fields
Mohamed Saidi, Akio Tamagawa
Given a number field and an integer , let denote the maximal -step solvable Galois extension of and write for the maximal -step solvable Galois…
Cyclic covers and Ihara's Question
Christopher Rasmussen, Akio Tamagawa
Let be a rational prime and a number field. Given a superelliptic curve of -power degree, we describe the field generated by the -power torsion of the…
A refined version of Grothendieck's anabelian conjecture for hyperbolic curves over finite fields
Mohamed Saidi, Akio Tamagawa
In this paper we prove a refined version of a theorem by Tamagawa and Mochizuki on isomorphisms between (tame) arithmetic fundamental groups of hyperbolic curves over finite fields…
Geometric monodromy -- semisimplicity and maximality
Anna Cadoret, Chun Yin Hui, Akio Tamagawa
Let be a connected scheme, smooth and separated over an algebraically closed field of characteristic , let be a smooth proper morphism and a…
A refined version of Grothendieck's birational anabelian conjecture for curves over finite fields
Mohamed Saidi, Akio Tamagawa
In this paper we prove a refined version of Uchida's theorem on isomorphisms between absolute Galois groups of global fields in positive characteristics, where one "ignores" the in…
