Diophantine Solutions Based Permutation for Image Encryption

open access: yesJournal of Algorithms & Computational Technology, 2013
A permutation technique based on the resolution of the system of three independent Diophantine equations is presented. Each Diophantine equation parameters are two positive integers generated from a chaotic system.

Diophantine equation $\frac{q^n-1}{q-1}=y$ for four prime divisors of $y-1$

open access: yes, 2005
summary:In this paper the special diophantine equation $\frac{q^{n}-1}{q-1}=y$ with integer coefficients is discussed and integer solutions are sought. This equation is solved completely just for four prime divisors of $y-1$

Multiplicative Diophantine equations

open access: yesJournal of Number Theory, 1992
The solution of the diophantine equation \(\prod_{i=1}^ n x_ i= \prod_{i=1}^ n y_ i\) is given in terms of \(n^ 2\) parameters (Bell's theorem) [cf. the first author, Proc. Ramanujan Cent. Int. Conf., Annamalainagar/India 1987, RMS Publ. 1, 141-146 (1988; Zbl 0696.10014)].

On a quartic diophantine equation

open access: yes, 1996
In this paper we consider the quartic diophantine equation 3(y2 – 1) = 2x2(x2 – 1) in integers x and y. We show that this equation does not have any other solutions (x, y) with x¿0 than those given by x = 0,1,2,3,6,91.

On the Diophantine Equation x2 – kxy + ky2 + ly = 0, l = 2n

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2017
We consider the Diophantine equation x2-kxy+ky2+ ly = 0 for l = 2n and determine for which values of the odd integer k, it has a positive integer solution x and y.

On a Diophantine equation of Erdös

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 1994
The second lemma is not proved in the quoted paper. It would lead to a polynomial bound in the height of the binary form. Despite this the main results can be true.

On Diophantine equations involving Lucas sequences

open access: yesOpen Mathematics, 2019
In this paper, we shall study the Diophantine equation un = R(m)P(m)Q(m), where un is a Lucas sequence and R, P and Q are polynomials (under weak assumptions).

Positive solutions of the diophantine equation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
Integral solutions of x3+λy+1−xyz=0 are observed for all integral λ. For λ=2 the 13 solutions of the equation in positive integers are determined. Solutions of the equation in positive integers were previously determined for the case λ=1.
