On Grothendieck's section conjecture for curves of index $1$

Algebraic Geometry 2023-05-18 v1 Number Theory

Abstract

We prove that every hyperbolic curve with a faithful action of a non-cyclic pp-group (with a few exceptions if p=2p=2) has a twisted form of index 11 which satisfies Grothendieck's section conjecture. Furthermore, we prove that for every hyperbolic curve SS over a field kk finitely generated over Q\mathbb{Q} there exists a finite extension K/kK/k and a finite \'etale cover CSKC\to S_{K} such that CC satisfies the conjecture.
