Répartition modulo 1 dans un corps de séries formelles sur un corps fini

Mireille Car (1995)

Acta Arithmetica

Introduction. Soit q une puissance d’un nombre premier p et soit q le corps fini à q éléments. Une certaine analogie entre l’arithmétique de l’anneau ℤ des entiers rationnels et celle de l’anneau q [ T ] a conduit à étendre à q [ T ] de nombreuses questions de l’arithmétique classique. L’équirépartition modulo 1 est une de ces questions. Le corps des nombres réels est alors remplacé par le corps q ( ( T - 1 ) ) des séries de Laurent formelles, complété du corps q ( T ) des fractions rationnelles pour la valuation à l’infini et...

Sidon basis in polynomial rings over finite fields

Wentang Kuo, Shuntaro Yamagishi (2021)

Czechoslovak Mathematical Journal

Let 𝔽 q [ t ] denote the polynomial ring over 𝔽 q , the finite field of q elements. Suppose the characteristic of 𝔽 q is not 2 or 3 . We prove that there exist infinitely many N such that the set { f 𝔽 q [ t ] : deg f < N } contains a Sidon set which is an additive basis of order 3 .

Some Algebraic Properties of Polynomial Rings

Christoph Schwarzweller, Artur Korniłowicz (2016)

Formalized Mathematics

In this article we extend the algebraic theory of polynomial rings, formalized in Mizar [1], based on [2], [3]. After introducing constant and monic polynomials we present the canonical embedding of R into R[X] and deal with both unit and irreducible elements. We also define polynomial GCDs and show that for fields F and irreducible polynomials p the field F[X]/ is isomorphic to the field of polynomials with degree smaller than the one of p.

Sur la transcendance de la série formelle Π

Jean-Paul Allouche (1990)

Journal de théorie des nombres de Bordeaux

En utilisant le théorème de Christol, Kamae, Mendès France et Rauzy, nous donnons une démonstration élémentaire de la transcendance de la série formelle Π ainsi que d’autres séries formelles à coefficients dans un corps fini.

Sur le développement en fraction continue d’une généralisation de la cubique de Baum et Sweet

Alina Firicel (2010)

Journal de Théorie des Nombres de Bordeaux

En 1976, Baum et Sweet ont donné le premier exemple d’une série formelle algébrique de degré 3 sur 𝔽 2 ( T ) ayant un développement en fraction continue dont les quotients partiels sont tous des polynômes en T de degré 1 ou 2 . Cette série formelle est l’unique solution dans le corps 𝔽 2 ( ( T - 1 ) ) de l’équation T X 3 + X - T = 0 . En 1986, Mills et Robbins ont décrit un algorithme permettant de calculer le développement en fraction continue de la série de Baum et Sweet.Dans cet article, nous considérons les équations plus générales...

Terne di quadrati consecutivi in un campo di Galois

Umberto Bartocci, Emanuela Ughi (1981)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Explicit formulae for the number of triplets of consecutive squares in a Galois field F q are given.

The fluctuations in the number of points on a family of curves over a finite field

Maosheng Xiong (2010)

Journal de Théorie des Nombres de Bordeaux

Let l 2 be a positive integer, 𝔽 q a finite field of cardinality q with q 1 ( mod l ) . In this paper, inspired by [6, 3, 4] and using a slightly different method, we study the fluctuations in the number of 𝔽 q -points on the curve F given by the affine model F : Y l = F ( X ) , where F is drawn at random uniformly from the set of all monic l -th power-free polynomials F 𝔽 q [ X ] of degree d as d . The method also enables us to study the fluctuations in the number of 𝔽 q -points on the same family of curves arising from the set of monic irreducible...

The joint distribution of Q -additive functions on polynomials over finite fields

Michael Drmota, Georg Gutenbrunner (2005)

Journal de Théorie des Nombres de Bordeaux

Let K be a finite field and Q K [ T ] a polynomial of positive degree. A function f on K [ T ] is called (completely) Q -additive if f ( A + B Q ) = f ( A ) + f ( B ) , where A , B K [ T ] and deg ( A ) &lt; deg ( Q ) . We prove that the values ( f 1 ( A ) , ... , f d ( A ) ) are asymptotically equidistributed on the (finite) image set { ( f 1 ( A ) , ... , f d ...
