Some results on one type of graph family with some special number sequences

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
In this study, we introduce a new graph family. Then, we calculate eigenvalues of the adjacency and the Laplacian matrix of this graph family. Moreover, we show that the perfect matching number of this graph family equals to special second order ...

Fermatian row and column sums as a family of generalized integers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this paper, we introduce some feature of the Fermatian numbers. The finite sum formulas of these numbers is calculate. The exponential generating function of Fermatian numbers is found and some of its identities is calculated.

On (k1A1, k2A2, k3A3)-Edge Colourings in Graphs and Generalized Jacobsthal Numbers

open access: yesAnnales Mathematicae Silesianae
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

Distance between consecutive elements of the multiplicative group of integers modulo n [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
For a prime number p, we consider its primorial P:=p# and U(P):=(ℤ/Pℤ)^× the set of elements of the multiplicative group of integers modulo P which we represent as points anticlockwise on a circle of perimeter P.

Relations Established Between Hypergeometric Functions and Some Special Number Sequences

open access: yesAxioms
In this paper, we establish new hypergeometric representations for two classical integer sequences, namely the Pell and Jacobsthal sequences. Motivated by Dilcher’s hypergeometric formulations of the Fibonacci sequence, we extend this framework to other ...
