Ramified covers of abelian varieties over torsion fields

L Bary-Soroker, A Fehm, S Petersen - Journal für die reine und …, 2023 - degruyter.com
We study rational points on ramified covers of abelian varieties over certain infinite Galois
extensions of ℚ. In particular, we prove that every elliptic curve E over ℚ has the weak …

Free subgroups of finitely generated free profinite groups

M Shusterman - Journal of the London Mathematical Society, 2016 - academic.oup.com
We give new and improved results on the freeness of subgroups of free profinite groups: A
subgroup containing the normal closure of a finite word in the elements of a basis is free; …

Primitive recursive decidability for large rings of algebraic integers inside the compositum of all symmetric extensions of ℚ

A Razon - Israel Journal of Mathematics, 2023 - Springer
Let ℚsymm be the compositum of all finite Galois extensions of ℚ with symmetric Galois
groups. Denote the absolute Galois group of ℚ by Gal (ℚ). For each σ=(σ 1,… σ e)∈ Gal (ℚ) …

Extensions of Hilbertian rings

M Jarden, A Razon - Glasgow Mathematical Journal, 2020 - cambridge.org
We generalize known results about Hilbertian fields to Hilbertian rings. For example, let R be
a Hilbertian ring (eg R is the ring of integers of a number field) with quotient field K and let A …
