The Number of Partitions of a Set and Superelliptic Diophantine Equations [PDF]
In this chapter we start by presenting some key results concerning the number of ordered k-partitions of multisets with equal sums. For these we give generating functions, recurrences and numerical examples.

A Linear Diophantine Fuzzy Graph-Theoretic Approach for Planar Dynamic Traffic Optimization
Dynamic urban traffic signal control systems face uncertainties such as fluctuating vehicle densities, unpredictable incidents, and varying driver behaviors, making precise decision-making highly challenging.

On the Relationship Between Matiyasevich's and Smorynski's Theorems
Let R be a non-zero subring of Q with or without 1. We assume that for every positive integer n there exists a computable surjection from N onto Rn. Every R \in {Z,Q} satisfies these conditions.

Integrality and the Laurent phenomenon for Somos 4 and Somos 5 sequences [PDF]
Somos 4 sequences are a family of sequences defined by a fourth-order quadratic recurrence relation with constant coefficients. For particular choices of the coefficients and the four initial data, such recurrences can yield sequences of integers.

Formulae are given furnishing all non-trivial integer solutions of the equation \[ (x^2-t^2)(y^2-t^2)=\biggl(\biggl({y-x\over 2}\biggr)^2-t^2\biggr)^2 \] considered for \(t=1\) by the reviewer and \textit{W. Sierpiński} [Elem. Math. 18, 132--133 (1963; Zbl 0126.07301)].

A Diophantine equation appearing in Diophantine approximation
All Diophantine equations \(ax^2+ by^2+ cz^2= 1+dxyz\) with \(a,b,c,d\in \mathbb{N}\) and \(a\mid d\), \(b\mid d\), \(c\mid d\), with solutions \((x,y,z)\in \mathbb{N}^3\) are classified. Equations of this type occur in connection with the approximation spectrum for quaternions.

On Diophantine singlefold specifications
Summary: Consider an \((m+1)\)-ary relation \(\mathcal{R}\) over the set \(\mathbb{N}\) of natural numbers. Does there exist an arithmetical formula \(\varphi (a_0, \ldots, a_m, x_1, \ldots, x_k)\), not involving universal quantifiers, negation, or implication, such that representation and univocity conditions, viz., \[ \begin{aligned} \mathcal{R ...
