On the Lichtenberg hybrid quaternions [PDF]

open access: yesMathematica Moravica
In this study, we define Lichtenberg hybrid quaternions. We give the Binet's formula, the generating functions, exponential generating functions and sum formulas of these quaternions. We find some relations between Jacobsthal hybrid quaternions, Mersenne

A Generalization of Gaussian Balancing and Gaussian Balancing‐Lucas Numbers With Applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this paper, we study a generalization of Gaussian balancing and Gaussian Lucas‐balancing numbers, we find their generating functions, Binet formulas, related matrix representation, and many other properties. Also, we provide some applications in cryptography.

VanderLaan Circulant Type Matrices

open access: yesAbstract and Applied Analysis, Volume 2015, Issue 1, 2015., 2015
Circulant matrices have become a satisfactory tools in control methods for modern complex systems. In the paper, VanderLaan circulant type matrices are presented, which include VanderLaan circulant, left circulant, and g‐circulant matrices. The nonsingularity of these special matrices is discussed by the surprising properties of VanderLaan numbers. The

On k-Jacobsthal and k-Jacobsthal-Lucas hybrid numbers

open access: yesJournal of Discrete Mathematical Sciences and Cryptography, 2021
In this paper, we consider the k-Jacobsthal and k-Jacobsthal-Lucas hybrid numbers. We obtain the Binet formulas, generating functions, exponential generating functions and summation formulas of k-J...

‘A wonderful day and a wonderful crossing!’: Internment (im)mobilities, ambivalence, and the residual tourist gaze in Second World War Britain

open access: yesTransactions of the Institute of British Geographers, Volume 50, Issue 3, September 2025.
Short Abstract 1940 saw the mass internment of so‐called ‘enemy aliens’ within Britain; this meant that innocent civilians were incarcerated in camps across the country, particularly within the tourist spaces of the Isle of Man. We interrogate how the holiday—as a geography of ideas, spaces, practices movements and sensibilities—became a frame of ...

Qualitative Behavior of Bidimensional Rational Fuzzy Difference Equations

open access: yesAbstract and Applied Analysis, Volume 2025, Issue 1, 2025.
This paper aims to extend the research conducted by Yalçınkaya et al. on one‐dimensional dynamics, specifically, their work titled “Qualitative behavior of a higher‐order fuzzy difference equation.” The purpose of this study is to expand the analysis of fuzzy difference equations into a bidimensional framework.

Some bounds for the spectral norms of some circulant matrices with generalized Jacobsthal–Lucas numbers

open access: yesMathematics Open
The purpose of this paper is to investigate the bounds of the spectral norms of some circulant matrices whose elements are a generalization of Jacobsthal–Lucas numbers called bi-periodic Jacobsthal–Lucas numbers by three different ways.

The Adjacency Matrix of One Type of Directed Graph and the Jacobsthal Numbers and Their Determinantal Representation

open access: yesJournal of Applied Mathematics, 2012
Recently there is huge interest in graph theory and intensive study on computing integer powers of matrices. In this paper, we consider one type of directed graph. Then we obtain a general form of the adjacency matrices of the graph.

Horadam Spinors

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
Spinors can be expressed as Lie algebra of infinitesimal rotations. Spinors are also defined as elements of a vector space which carries a linear representation of the Clifford algebra typically. The motivation for this study is to define a new and particular sequence.
