Practice of the Incomplete $p$-Ramification Over a Number Field -- History of Abelian $p$-Ramification

open access: yesCommunications in Advanced Mathematical Sciences, 2019
The theory of $p$-ramification, regarding the Galois group of the maximal pro-$p$-extension of a number field $K$, unramified outside $p$ and $\infty$, is well known including numerical experiments with PARI/GP programs.

DIFFERENTIATION OF POLYNOMIALS IN SEVERAL VARIABLES OVER GALOIS FIELDS OF FUZZY CARDINALITY AND APPLICATIONS TO REED-MULLER CODES

open access: yesAdvanced Engineering Research, 2018
Introduction. Polynomials in several variables over Galois fields provide the basis for the Reed-Muller coding theory, and are also used  in a number of cryptographic problems.

Quadratic subfields on quartic extensions of local fields

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
We show that any quartic extension of a local field of odd residue characteristic must contain an intermediate field. A consequence of this is that local fields of odd residue characteristic do not have extensions with Galois group A4 or S4 ...

Quasifinite fields of prescribed characteristic and Diophantine dimension

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let ℙ be the set of prime numbers, ℙ the union ℙ ∪ {0}, and for any field E, let char(E) be its characteristic, ddim(E) the Diophantine dimension of E, 𝒢E the absolute Galois group of E, and cd(𝒢E) the Galois cohomological dimension 𝒢E.

Classification and Construction of (k,3)-Arcs on Projective Plane Over Galois Field GF(7)

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
  The purpose of this work is to study the classification and construction of (k,3)-arcs in the projective plane PG(2,7). We found that there are two (5,3)-arcs, four (6,3)-arcs, six (7,3)arcs, six (8,3)-arcs, seven (9,3)-arcs, six (10,3)-arcs and six ...
