Quartic index form equations and monogenizations of quartic orders [PDF]

open access: yesEssential Number Theory, 2022
Some upper bounds for the number of monogenizations of quartic orders are established by considering certain classical Diophantine equations, namely index form equations in quartic number fields, and cubic and quartic Thue equations.

On a class of quartic Diophantine equations

open access: yes, 2021
In this paper, by using elliptic curves theory, we study the quartic Diophantine equation (DE) ∑n i=1 aix 4 i = ∑n j=1 ajy 4 j , where ai and n ≥ 3 are fixed arbitrary integers. We try to transform this quartic to a cubic elliptic curve of positive rank.

Enumerative Galois theory for cubics and quartics [PDF]

open access: yes, 2020
We show that there are $O_\varepsilon(H^{1.5+\varepsilon})$ monic, cubic polynomials with integer coefficients bounded by $H$ in absolute value whose Galois group is $A_3$.

Integral points on a certain family of elliptic curves [PDF]

open access: yes, 2015
The Thue-Siegel method is used to obtain an upper bound for the number of primitive integral solutions to a family of quartic Thue's inequalities. This will provide an upper bound for the number of integer points on a family of elliptic curves with j ...

On a class of quartic Diophantine equations of at least five variables

open access: yesNotes on Number Theory and Discrete Mathematics, 2018
In this paper, elliptic curves theory is used for solving the quartic Diophantine equation X + Y 4 = 2U + ∑n i=1 TiU 4 i , where n ≥ 1, and Ti, are rational numbers.

The lost proof of Fermat's last theorem

open access: yes, 2021
This work contains two papers: the first entitled "Euler's double equations equivalent to Fermat's Last Theorem" presents a marvellous "Eulerian" proof of Fermat's Last Theorem, which could have entered in a not very narrow margin, i.e.

Universal Calabi-Yau Algebra: Classification and Enumeration of Fibrations [PDF]

open access: yes, 2002
We apply a universal normal Calabi-Yau algebra to the construction and classification of compact complex $n$-dimensional spaces with SU(n) holonomy and their fibrations.

Constructions of diagonal quartic and sextic surfaces with infinitely many rational points

open access: yes, 2014
In this note we construct several infinite families of diagonal quartic surfaces \begin{equation*} ax^4+by^4+cz^4+dw^4=0, \end{equation*} where $a,b,c,d\in\Z\setminus\{0\}$ with infinitely many rational points and satisfying the condition $abcd\neq ...
