Introduction to generalized Leonardo-Alwyn hybrid numbers ARXIV: 2405.13074

In [6], Gökbaş defined a new type of number sequence called Leonardo-Alwyn sequence. In this paper, we consider the generalized Leonardo-Alwyn hybrid numbers and investigate some of their properties. We also give some applications related to the generalized Leonardo-Alwyn hybrid numbers in matrices.

On some Properties of Generalized Tribonacci Spinors ARXIV: 2404.11620 

Spinors are used in physics quite extensively. The goal of this study is also the spinor structure lying in the basis of the quaternion algebra. In this paper, first, we have introduced spinors mathematically. Then, we have defined Tribonacci spinors using the generalized Tribonacci quaternions. Later, we have established the structure of algebra for these spinors. Finally, we have proved some important formulas such as Binet and Cassini-like formulas which are given for some series of numbers in mathematics for Tribonacci spinors.

Quadratic Approximation of Generalized Tribonacci Numbers. Discussiones Mathematicae-General Algebra and Applications, 32(2), (2018), 227-237.

ABSTRACT. In this paper, we give quadratic approximation of generalized Tribonacci sequence {Vn}n≥0 defined by Vn = rVn−1 + sVn−2 + tVn−3 (n ≥ 3) and use this result to give the matrix form of the n-th power of a companion matrix of {Vn}n≥0. Then we re-prove the cubic identity or Cassini-type formula for {Vn}n≥0 and the Binet’s formula of the generalized Tribonacci quaternions.

ABSTRACT. In this paper, we present for the first time a sequence of quaternions of order 4 that we will call the fourth-order Jacobsthal and the fourth-order Jacobsthal-Lucas quaternions. This generalizes some previous results given by Szynal-Liana and Włoch in [13], Torunbalci Aydin and Yuce in [14] and Cerda-Morales in [2].
