Density of Arithmetic Representations of Function Fields [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
We propose a conjecture on the density of arithmetic points in the deformation space of representations of the \'etale fundamental group in positive characteristic. This?

Finiteness theorems for algebraic tori over function fields

open access: yesComptes Rendus. Mathématique, 2021
We present a number of finiteness results for algebraic tori (and, more generally, for algebraic groups with toric connected component) over two classes of fields: finitely generated fields and function fields of algebraic varieties over fields of type ...

Algebraic Persistent Fault Analysis of SKINNY_64 Based on S_Box Decomposition

open access: yesEntropy, 2022
Algebraic persistent fault analysis (APFA), which combines algebraic analysis with persistent fault attacks, brings new challenges to the security of lightweight block ciphers and has received widespread attention since its introduction.

Etale and crystalline companions, I [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
Let $X$ be a smooth scheme over a finite field of characteristic $p$. Consider the coefficient objects of locally constant rank on $X$ in $\ell$-adic Weil cohomology: these are lisse Weil sheaves in \'etale cohomology when $\ell \neq p$, and ...

Some Properties of Euler’s Function and of the Function τ and Their Generalizations in Algebraic Number Fields

open access: yesMathematics, 2021
In this paper, we find some inequalities which involve Euler’s function, extended Euler’s function, the function τ, and the generalized function τ in algebraic number fields.

Counting algebraic numbers in short intervals with rational points

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In 2012 it was proved that real algebraic numbers follow a non­uniform but regular distribution, where the respective definitions go back to H. Weyl (1916) and A. Baker and W. Schmidt (1970).

Developing Number Sense: An Approach to Initiate Algebraic Thinking in Primary Education

open access: yesMathematics, 2021
Traditionally, the teaching and learning of algebra has been addressed at the beginning of secondary education with a methodological approach that broke traumatically into a mathematical universe until now represented by numbers, with bad consequences ...

Arithmetic of Calabi-Yau Varieties and Rational Conformal Field Theory [PDF]

open access: yes, 2001
It is proposed that certain techniques from arithmetic algebraic geometry provide a framework which is useful to formulate a direct and intrinsic link between the geometry of Calabi-Yau manifolds and the underlying conformal field theory. Specifically it
