Fibonacci and Lucas Numbers with Applications

In this paper, we investigate the Fibonacci and Lucas quaternions. We give the generating functions and Binet formulas for these quaternions. Moreover, we derive some sums formulas for them.

On Fibonacci Quaternions

Horadam defined the Fibonacci quaternions and established a few relations for the Fibonacci quaternions. In this paper, we investigate the complex Fibonacci quaternions and give the generating function and Binet formula for these quaternions. Moreover, we also give the matrix representations of them.

On Complex Fibonacci Quaternions

The main object of this paper is to present a systematic investigation of new classes of quaternion numbers associated with the familiar Pell and Pell-Lucas numbers. The various results obtained here for these classes of quaternion numbers include recurrence relations, summation formulas and Binet’s formulas.

On Pell Quaternions and Pell-Lucas Quaternions

In this paper, we investigate some properties of generalized Fibonacci quaternions and Fibonacci-Narayana quaternions.
