In this paper we will study the families of triples $(u,v,w)$ of elements in a commutative ring $r$ with the property that $v\,w+n=\widetilde{u}^2$, $w\,u+n=\widetilde{v}^2$ and $u\,v+n=\widetilde{w}^2$ for some $n, ...

Generalized Tribonacci Sequence and its Sum Through Third Order Difference Operator
2024 International Conference on Science, Engineering and Business for Driving Sustainable Development Goals (SEB4SDG)This study presents the generalized third-order difference operator with constant coefficients and inverse, allowing us to construct a sequence similar to the generalized k-Fibonacci sequence.

Fixed points of automorphisms of certain finite groups
International Journal of Algebra, 2019Let G = Zp2 × Zp3 be a finite group of order p5. Suppose that d is a divisor of the order of group G. In this article, we enumerated all automorphisms of G fixing d elements of G and denote them by Θ(G, d), we characterize the automorphism group as 2 by ...

Some results on a generalized bi-periodic Lucas sequence
, 2020In this paper we consider a generalized bi-periodic Lucas sequence introduced by Bilgici. For this sequence we derive the Catalan’s identity and Gelin-Cesàro identity.

Recurrences for Entries of Powers of Matrices
The Fibonacci quarterly, 2017In this note, giving course to a challenge in a recent paper of Larcombe [2], we find the entries of any nth power of a 3×3 matrix, and as a byproduct, we recover Larcombe’s result on 2× 2 matrices.
