Belyi`s Theorem-IV
Ali Sinan Sertöz
Bilkent University, Türkiye
In the previous talks, the proof of Belyi's theorem was completed modulo a finiteness criterion. In this talk we will prove that criterion. Namely, we will prove that a compact Riemann surface S is defined over the algebraic numbers Q¯ if and only if the orbit of S under the action of the Galois group Gal(C/Q) is finite.
