If a machine did it, it is probably transcendental (even -adically)

Laura Capuano, Sara Checcoli, Marzio Mula +1

Continued fraction expansions provide a well-established bridge between algebraic properties of numbers and combinatorics on words. In this article, we investigate the algebraicity…

p-Adically convergent loci in varieties arising from periodic continued fractions

Laura Capuano, Marzio Mula, Lea Terracini +1

Inspired by several alternative definitions of continued fraction expansions for elements in , we study -adically convergent periodic continued fractions with parti…

On -adic continued fractions with extraneous denominators: some explicit finiteness results

Laura Capuano, Sara Checcoli, Marzio Mula +1

Let be a number field. We show that, up to allowing a finite set of denominators in the partial quotients, it is possible to define algorithms for -adic continued…

Quaternionic -adic continued fractions

Laura Capuano, Marzio Mula, Lea Terracini

We develop a theory of -adic continued fractions for a quaternion algebra over ramified at a rational prime . Many properties holding in the commutative case…

Greatest Common Divisor results on semiabelian varieties and a Conjecture of Silverman

Fabrizio Barroero, Laura Capuano, Amos Turchet

A divisibility sequence is a sequence of integers such that divides if divides . Results of Bugeaud, Corvaja, Zannier, among others, have shown that th…

Betti maps, Pell equation in polynomials and almost Belyi maps

Fabrizio Barroero, Laura Capuano, Umberto Zannier

We study the Betti map of a particular (but relevant) section of the family of Jacobians of hyperelliptic curves using the polynomial Pell equation , with $A,B,D\in \ma…

On the finiteness of -adic continued fractions for number fields

Laura Capuano, Nadir Murru, Lea Terracini

For a prime ideal of the ring of integers of a number field , we give a general definition of -adic continued fraction, which also includes classica…

On periodicity of -adic Browkin continued fractions

Laura Capuano, Nadir Murru, Lea Terracini

The classical theory of continued fractions has been widely studied for centuries for its important properties of good approximation, and more recently it has been generalized to $…

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

Fabrizio Barroero, Laura Capuano, László Mérai +2

For positive integers and , we introduce and study the notion of -multiplicative dependence over the algebraic closure of a finite prime field $…

A note on cyclotomic polynomials and Linear Feedback Shift Registers

Laura Capuano, Antonio J. Di Scala

Linear Feedback Shift Registers (LFRS) are tools commonly used in cryptography in many different context, for example as pseudo-random numbers generators. In this paper we characte…

An effective criterion for periodicity of l-adic continued fractions

Laura Capuano, Francesco Veneziano, Umberto Zannier

The theory of continued fractions has been generalized to l-adic numbers by several authors and presents many differences with respect to the real case. In the present paper we inv…

Upper ramification jumps in abelian extensions of exponent p

Laura Capuano, Ilaria Del Corso

In this paper we present a classification of the possible upper ramification jumps for an elementary abelian p-extension of a p-adic field. The fundamental step for the proof of th…
