A sparsity result for the Dynamical Mordell-Lang Conjecture in positive characteristic

Dragos Ghioca, Alina Ostafe, Sina Saleh +1

We prove a quantitative partial result in support of the Dynamical Mordell-Lang Conjecture (also known as the DML conjecture) in positive characteristic. More precisely, we show th…

Multiplicative and linear dependence in finite fields and on elliptic curves modulo primes

Fabrizio Barroero, Laura Capuano, László Mérai +2

For positive integers $K$ and $L$ , we introduce and study the notion of $K$ -multiplicative dependence over the algebraic closure $F_{p}$ of a finite prime field $…

On the Skolem problem and some related questions for parametric families of linear recurrence sequences

Alina Ostafe, Igor Shparlinski

We show that in a parametric family of linear recurrence sequences $a_{1} (α) f_{1} (α)^{n} + \dots + a_{k} (α) f_{k} (α)^{n}$ with the coefficients $a_{i}$ and characteristic roots $f_{i}$ , $i=1, \l…
