Sur l'existence du sch\'ema en groupes fondametal [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2020
Let $S$ be a Dedekind scheme, $X$ a connected $S$-scheme locally of finite type and $x\in X(S)$ a section. The aim of the present paper is to establish the existence of the fundamental group scheme of $X$, when $X$ has reduced fibers or when $X$ is ...

Construction of Complex Lattice Codes via Cyclotomic Fields

open access: yesTrends in Computational and Applied Mathematics, 2022
Through algebraic number theory and Construction $A$ we extend an algebraic procedure which generates complex lattice codes from the polynomial ring \mathbb{F}_{2}[x]/(x^{n}-1), where \mathbb{F}_{2}=\{0,1\}, by using ideals from the generalized ...

Autour de la conjecture de Tate enti\`ere pour certains produits de dimension $3$ sur un corps fini [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
Let $X$ be the product of a surface satisfying $b_2=\rho$ and of a curve over a finite field. We study a strong form of the integral Tate conjecture for $1$-cycles on $X$.

Formal deformations of the algebra of Jacobi forms and Rankin–Cohen brackets

open access: yesComptes Rendus. Mathématique, 2021
This work is devoted to the algebraic and arithmetic properties of Rankin–Cohen brackets allowing to define and study them in several natural situations of number theory.

Variation of stable birational types in positive characteristic [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2020
Let k be an uncountable algebraically closed field and let Y be a smooth projective k-variety which does not admit a decomposition of the diagonal. We prove that Y is not stably birational to a very general hypersurface of any given degree and dimension.

Degree of the Product of Two Algebraic Numbers One of Which Is of Prime Degree

open access: yesMathematics, 2023
Let α and β be two algebraic numbers such that deg(α)=m and deg(β)=p, where p is a prime number not dividing m. This research is focused on the following two objectives: to discover new conditions under which deg(αβ)=mp; to determine the complete list of

A Topological Perspective on Interacting Algebraic Theories [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
Techniques from higher categories and higher-dimensional rewriting are becoming increasingly important for understanding the finer, computational properties of higher algebraic theories that arise, among other fields, in quantum computation.

GiANT: Graphical Algebraic Number Theory [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
While most algebra is done by writing text and formulas, diagrams have always been used to present structural information clearly and concisely. Text shells are the de facto interface for computational algebraic number theory, but they are incapable of presenting structural information graphically.

A construction of the polylogarithm motive [PDF]

open access: yesÉpijournal de Géométrie Algébrique
Classical polylogarithms give rise to a variation of mixed Hodge-Tate structures on the punctured projective line $S=\mathbb{P}^1\setminus \{0, 1, \infty\}$, which is an extension of the symmetric power of the Kummer variation by a trivial variation.
