Cryptographical Applications of Linear Transformations and Pell Equations: An R-Based Approach
Objective: This article’s main aim is to encrypt and decrypt the message to be sent using matrices of the linear transformation and the fundamental solution of the Pell equation. R Programming is provided at the end of the article.

Eulerian polynomials as moments, via exponential Riordan arrays [PDF]
Using the theory of exponential Riordan arrays and orthogonal polynomials, we demonstrate that the "descending power" Eulerian polynomials, and their once shifted sequence, are moment sequences for simple families of orthogonal polynomials, which we ...

On Doubled and Quadrupled Fibonacci Type Sequences
In this paper we study a family of doubled and quadrupled Fibonacci type sequences obtained by distance generalization of Fibonacci sequence. In particular we obtain doubled Fibonacci sequence, doubled and quadrupled Padovan sequence and quadrupled ...

Some Determinants Involving Incomplete Fubini Numbers
We study some properties of restricted and associated Fubini numbers. In particular, they have the natural extensions of the original Fubini numbers in the sense of determinants.

Some conjectures on the ratio of Hankel transforms for sequences and series reversion [PDF]
For each element of certain families of integer sequences, we study the term-wise ratios of the Hankel transforms of three sequences related to that element by series reversion.

Square Roots of Real 3 × 3 Matrices vs. Quartic Polynomials with Real Zeros
There is an interesting analogy between the description of the real square roots of 3×3 matrices and the zeros of the (depressed) real quartic polynomials.

Unit group of the ring of negacirculant matrices over finite commutative chain rings
Circulant matrices form an important class of matrices that have been continuously studied due to their nice algebraic structures and wide applications. In this study, we focus specifically on negacirculant matrices, which are known as extensions of the ...

On (k1A1, k2A2, k3A3)-Edge Colourings in Graphs and Generalized Jacobsthal Numbers
In this paper we introduce a new kind of generalized Jacobsthal numbers in a distance sense. We give the identities and matrix representations for them and their connections with the Fibonacci and the Pell numbers. We also describe the interpretations of
