Padovan and Perrin numbers of the form 7ᵗ-5ᶻ-3ʸ-2ˣ [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Consider the Padovan sequence (pₙ)ₙ≥₀ given by pₙ₊₃=pₙ₊₁+pₙ with p₀=p₁=p₂=1. Its companion sequence, the Perrin sequence (℘ₙ)ₙ≥₀, follows the same recursive formula as the Padovan numbers, but with different initial values: p₀=3, p₁=0 and p₂=2.

Exponential Diophantine equations for correlation functions of the Tchebyscheff maps

open access: yes四川大学学报. 自然科学版, 2023
Tchebyscheff maps are typical chaotic maps. Correlation functions play a key role in the study of their statistical properties. This paper aims at the solutions of a class of exponential Diophantine equations arising in the calculation of correlation ...

A Hasse-type principle for exponential Diophantine equations and its applications [PDF]

open access: yes, 2016
We propose a conjecture, similar to Skolem's conjecture, on a Hasse-type principle for exponential Diophantine equations. We prove that in a sense the principle is valid for "almost all" equations.

Classical and modular approaches to exponential Diophantine equations - II. The Lebesgue-Nagell equation [PDF]

open access: yes, 2006
This is the second in a series of papers where we combine the classical approach to exponential Diophantine equations (linear forms in logarithms, Thue equations, etc.) with a modular approach based on some of the ideas of the proof of Fermat's Last ...

Exponential sums equations and tropical geometry [PDF]

open access: yes, 2023
Zilber’s Exponential-Algebraic Closedness Conjecture states that algebraic varieties in Cn×(C×)n intersect the graph of complex exponentiation, unless that contradicts the algebraic and transcendence properties of exp.

Heights and multiplicative relations on algebraic varieties [PDF]

open access: yes, 2007
Points on a subvariety X of a semi-abelian variety A that are contained in a subgroup, let the subgroup be of finite rank or algebraic, are subject to severe restrictions arithmetical nature. Finiteness results for intersections of X with subgroups of

Exponential diophantine equations in rings of positive characteristic [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2020
In this paper, we prove an algorithmical solvability of exponential-Diophantine equations in rings represented by matrices over fields of positive characteristic. Consider the system of exponential-Diophantine equations [Formula: see text] where [Formula: see text] are constants from matrix ring of characteristic [Formula: see text], [Formula: see ...

Diophantine equations after Fermat’s last theorem [PDF]

open access: yes, 2009
The author considers the following two questions: {\parindent=7mm \item{(i)}Given a Diophantine equation, what information can be obtained by following the strategy of Wiles' proof of Fermat's last theorem?

A number theoretic method for high order correlations of the Ulam map

open access: yes四川大学学报. 自然科学版, 2020
In this paper, a number theoretic method is introduced to calculate the high order correlation functions of the Ulam map. In this method, the calculation is firstly transformed into solving a class of exponential Diophantine equations with variable ...

On a conjecture on exponential Diophantine equations [PDF]

open access: yesActa Arithmetica, 2009
We study the solutions of a Diophantine equation of the form $a^x+b^y=c^z$, where $a\equiv 2 \pmod 4$, $b\equiv 3 \pmod 4$ and $\gcd (a,b,c)=1$. The main result is that if there exists a solution $(x,y,z)=(2,2,r)$ with $r>1$ odd then this is the only solution in integers greater than 1, with the possible exception of finitely many values $(c,r)$. We
