Cubic Diophantine inequalities [PDF]

open access: yesMathematika, 1995
\textit{H. Davenport} and \textit{K. F. Roth} [Mathematika, 2, 81--96 (1955; Zbl 0066.29301)] showed that for \(s \geq 8\) the values of the real additive form \(\lambda_1 x^3_1 + \ldots + \lambda_s x^3_s\) on \(\mathbb{Z}^s\) are dense on the real line, provided that \(\lambda_1/ \lambda_2\) is irrational.

Cubic Diophantine inequalities [PDF]

open access: yesMathematika, 1982
Let \(\lambda_1,\ldots,\lambda_s\) be non-zero real numbers and not all ratios \(\lambda_i/\lambda_j\) be rational. \textit{H. Davenport} and \textit{K. F. Roth} [Mathematika 2, 81--96 (1955; Zbl 0066.29301)] proved that the values taken by \(\lambda_1x^3_1+\cdots+\lambda_8x^3_8\) at integer points \(x_1,\ldots,x_8\), are dense on the real line. Later,

Quadratic Diophantine Inequalities

open access: yesJournal of Number Theory, 2001
The theme of this paper is to investigate certain systems of Diophantine inequalities on real diagonal quadratic forms. First, let \(Q_1\) and \(Q_2\) be real diagonal quadratic forms in \(s\) variables, with \(s\geq 10\), and suppose that whenever \(\alpha\) and \(\beta\) are real numbers with \((\alpha,\beta)\neq(0,0)\), then the form \(\alpha Q_1 ...

Diophantine Inequalities for Polynomial Rings

open access: yesJournal of Number Theory, 1999
The author studies the Hardy-Littlewood method for the Laurent series field \(\mathbb F_q ((1/T))\) over the finite field \(\mathbb F_q\) with \(q\) elements. He shows that if \(\lambda_1\), \(\lambda_2\), \(\lambda_3\) are nonzero elements in \(\mathbb F_q ((1/T))\) satisfying \(\lambda_1/\lambda_2\not\in \mathbb F_q(T)\) and \(\text{sgn} (\lambda_1)+

Proportionally modular diophantine inequalities

open access: yesJournal of Number Theory, 2003
The authors study the sets of nonnegative solutions of Diophantine inequalities of the form \(ax\) mod \(b \leq cx\) with \(a, b\) and \(c\) positive integers. These sets are numerical semigroups, which are investigated and characterized.

On pairs of cubic Diophantine inequalities

open access: yesMathematika, 1991
\textit{H. Davenport} and \textit{H. Heilbronn} [J. Lond. Math. Soc. 21, 185--193 (1946; Zbl 0060.11914)] proved that if \(Q({\mathbf x})=\sum^5_{j=1}\lambda_jx^2_j\) is an indefinite quadratic form with real coefficients \(\lambda_j\), such that at least one of the ratios \(\lambda_i/\lambda_j\) is irrational, then for any \(\varepsilon>0\) there ...

Cubic diophantine inequalities for split forms [PDF]

open access: yesMonatshefte Fur Mathematik, 2014
Denote by $s_0^{(r)}$ the least integer such that if $s \ge s_0^{(r)}$, and $F$ is a cubic form with real coefficients in $s$ variables that splits into $r$ parts, then $F$ takes arbitrarily small values at nonzero integral points. We bound $s_0^{(r)}$ for $r \le 6$.

Mersenne version of Brocard-Ramanujan equation

open access: yesJournal of New Results in Science, 2023
In this study, we deal with a special form of the Brocard-Ramanujan equation, which is one of the interesting and still open problems of Diophantine analysis.
