Topological Transcendental Fields

open access: yesAxioms, 2022
This article initiates the study of topological transcendental fields F which are subfields of the topological field C of all complex numbers such that F only consists of rational numbers and a nonempty set of transcendental numbers. F, with the topology

Prime Spectrum of the Ring of Adeles of a Number Field

open access: yesMathematics, 2022
Much is known about the adele ring of an algebraic number field from the perspective of harmonic analysis and class field theory. However, its ring-theoretical aspects are often ignored.

On simple modules with singular highest weights for so2l+1(K) [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
In this paper, we study formal characters of simple modules with singular highest weights over classical Lie algebras of type B over an algebraically closed field of characteristic p ≥ h, where h is the Coxeter number.

Necessary and sufficient conditions for the existence of invariant algebraic curves

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
We present a set of conditions enabling a polynomial system of ordinary differential equations in the plane to have invariant algebraic curves. These conditions are necessary and sufficient. Our main tools include factorizations over the field of Puiseux

Counting rational points of two classes of algebraic varieties over finite fields

open access: yesAIMS Mathematics, 2023
Let $ p $ stand for an odd prime and let $ \eta\in \mathbb Z^+ $ (the set of positive integers). Let $ \mathbb F_q $ denote the finite field having $ q = p^\eta $ elements and $ \mathbb F_q^* = \mathbb F_q\setminus \{0\} $.

Comparing the number of ideals in quadratic number fields

open access: yesMathematical Modelling and Control, 2022
Denote by $ a_{K}(n) $ the number of integral ideals in $ K $ with norm $ n $, where $ K $ is a algebraic number field of degree $ m $ over the rational field $ \mathcal{Q} $. Let $ p $ be a prime number.

Neutrosophic Quadruple Algebraic Codes over Z2 and their Properties [PDF]

open access: yesNeutrosophic Sets and Systems, 2020
In this paper we for the first time develop, define and describe a new class of algebraic codes using Neutrosophic Quadruples which uses the notion of known value, and three unknown triplets (T, I, F) where T is the truth value, I is the indeterminate ...
