Repdigits in the base $b$ as sums of four balancing numbers [PDF]

open access: yesMathematica Bohemica, 2021
The sequence of balancing numbers $(B_n)$ is defined by the recurrence relation $B_n=6B_{n-1}-B_{n-2}$ for $n\geq2$ with initial conditions $B_0=0$ and $B_1=1.$ $B_n$ is called the $n$th balancing number. In this paper, we find all repdigits in the base $

Integral geometry on discrete matrices

open access: yesMoroccan Journal of Pure and Applied Analysis, 2021
In this note, we study the Radon transform and its dual on the discrete matrices by defining hyperplanes as being infinite sets of solutions of linear Diophantine equations. We then give an inversion formula and a support theorem.

S-Restricted Compositions Revisited [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2017
An S-restricted composition of a positive integer n is an ordered partition of n where each summand is drawn from a given subset S of positive integers. There are various problems regarding such compositions which have received attention in recent years.

A New Algorithm Based on Colouring Arguments for Identifying Impossible Polyomino Tiling Problems

open access: yesAlgorithms, 2022
Checkerboard colouring arguments for proving that a given collection of polyominoes cannot tile a finite target region of the plane are well-known and typically applied on a case-by-case basis. In this article, we give a systematic mathematical treatment

Solution of Linear and Quadratic Equations Based on Triangular Linear Diophantine Fuzzy Numbers

open access: yesJournal of Function Spaces, 2021
This paper is introducing a new concept of triangular linear Diophantine fuzzy numbers (TLDFNs) in a generic way. We first introduce the concept of TLDFNs and then study the arithmetic operations on these numbers.

Linear systems of Diophantine equations

open access: yesThe Electronic Journal of Linear Algebra, 2022
Given free modules $M\subseteq L$ of finite rank $f\geq 1$ over a principal ideal domain $R$, we give a procedure to construct a basis of $L$ from a basis of $M$ assuming the invariant factors or elementary divisors of $L/M$ are known. Given a matrix $A\in M_{m,n}(R)$ of rank $r$, its nullspace $L$ in $R^n$ is a free $R$-module of rank $f=n-r$.

On Some Methods for Solution of Linear Diophantine Equations

open access: yesUniversal Journal of Mathematics and Applications, 2020
The paper considers a linear Diophantine equation. A method (algorithm) for finding a general class of solutions of equation is proposed. The proposed algorithm is explained by examples of equations with two and three variables, trying to direct the ...
