Fibonacci and Lucas numbers of the form -2^a-3^b-5^c+7^d

open access: yesRevista Integración
In this note we find all Fibonacci and Lucas numbers of the form -2^a-3^b-5^c+7^d where a, b, c, d are non-negative integers, with 0 ≤ max{a, b, c} ≤ d. This result gives an answer to a question posed by Qu, Zeng and Cao.

Linear forms in elliptic logarithms

open access: yesJournal of Number Theory, 1985
The author studies lower bounds for linear forms in elliptic integrals in the case of complex multiplications, and related estimates for dependence relations of such numbers. His results considerably improves on the previous works of D. Masser and M. Anderson on these topics, the main feature being a sharp dependence on the heights of the corresponding

Linear forms in the logarithms of three positive rational numbers [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 1997
In this paper we prove a lower bound for the linear dependence of three positive rational numbers under certain weak linear independence conditions on the coefficients of the linear forms. Let Λ=b 2 logα 2 -b 1 logα 1 -b 3 logα 3 ≠0 with b 1 ,b 2 ,b 3 positive integers and α 1 ,α 2 ,α 3 positive multiplicatively independent rational numbers greater ...

Model for allocating the share of the land component from the assessment of the market value of single real estate objects

open access: yesСтатистика и экономика
The objective of the study is to develop a mathematical model and corresponding methodology that allows, based on available empirical observations (market data), in a comparative approach, to create an assessment of the market value of a single real ...

Solving elliptic diophantine equations by estimating linear forms in elliptic logarithms [PDF]

open access: yesActa Arithmetica, 1994
In order to compute all integer points on a Weierstraß equation for an elliptic curve \(E/\mathbb{Q}\), one may translate the linear relation between rational points on \(E\) into a linear form of elliptic logarithms. An upper bound for this linear form can be obtained by employing the Néron-Tate height function and a lower bound is provided by a ...

On Algebraic Numbers of Small Height: Linear Forms in One Logarithm

open access: yesJournal of Number Theory, 1994
The authors establish a lower bound for \(|\alpha -1|\) where \(\alpha\) is a complex algebraic number \(\neq 1\). This lower bound is completely explicit in terms of the degree \(D\) of \(\alpha\) and its Mahler measure \(M(\alpha)\). Given any number \(\mu>0\) with \(\mu\geq \log M(\alpha)\), the authors prove \[ |\alpha -1|\geq \exp \Bigl\{- \bigl( \

Explicit lower bounds for linear forms in two logarithms [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
We give an explicit lower bound for linear forms in two logarithms. For this we specialize the so-called Schneider method with multiplicity described in [10]. We substantially improve the numerical constants involved in existing statements for linear forms in two logarithms, obtained from Baker’s method or Schneider’s method with multiplicity.

Matrices whose coefficients are linear forms in logarithms

open access: yesJournal of Number Theory, 1992
Denote by \(L\) the \({\mathbb{Q}}\)-vector space of complex numbers \(\ell\) such that \(e^{\ell}\) is an algebraic number, and by \({\mathcal L}\) the vector space generated by \(1\) and \(L\) over the field \(\overline\mathbb{Q}\) of algebraic numbers.
