Cyclotomic and abelian points in backward orbits of rational functions
A Ferraguti, A Ostafe, U Zannier - Advances in Mathematics, 2024 - Elsevier
We prove several results on backward orbits of rational functions over number fields. First,
we show that if K is a number field, ϕ∈ K (x) and α∈ K then the extension of K generated by …

Multiplicative dependence of rational values modulo approximate finitely generated groups
In this paper, we establish some finiteness results about the multiplicative dependence of
rational values modulo sets which are 'close'(with respect to the Weil height) to division …

Multiplicative and linear dependence in finite fields and on elliptic curves modulo primes
For positive integers and, we introduce and study the notion of-multiplicative dependence
over the algebraic closure of a finite prime field, as well as-linear dependence of points on …

Multiplicative dependence of the translations of algebraic numbers
A Dubickas, M Sha - Revista matemática iberoamericana, 2018 - ems.press
In this paper, we first prove that given pairwise distinct algebraic numbers α1,..., αn, the
numbers α1+ t,..., αn+ t are multiplicatively independent for all sufficiently large integers t …

Torsion points with multiplicatively dependent coordinates on elliptic curves
F Barroero, M Sha - Bulletin of the London Mathematical …, 2020 - Wiley Online Library
In this paper, we study the finiteness problem of torsion points on an elliptic curve whose
coordinates satisfy some multiplicative dependence relations. In particular, we prove that on …

A fusion variant of the classical and dynamical Mordell-Lang conjectures in positive characteristic
J Bell, D Ghioca - arXiv preprint arXiv:2205.02644, 2022 - arxiv.org
We study an open question at the interplay between the classical and the dynamical Mordell-
Lang conjectures in positive characteristic. Let $ K $ be an algebraically closed field of …

On multiplicatively dependent vectors of polynomial values
M Young - arXiv preprint arXiv:2402.13704, 2024 - arxiv.org
Given polynomials $ f_1,\ldots, f_n $ in $ m $ variables with integral coefficients, we give
upper bounds for the number of integral $ m $-tuples $\mathbf {u} _1,\ldots,\mathbf {u} _n …
