Abstract
The Fibonacci sequence $(F_n)$ and the Lucas sequence $(L_n)$ have a deep connection with certain matrices known as $Q$-matrices. The Fibonacci $Q$-matrix, $Q_F = \begin{bmatrix} 1 & 1 \\ 1 & 0 \end{bmatrix}$, is known for the fact that its $n$-th power satisfies$Q_F^n = \begin{bmatrix} F_{n+1} & F_n \\ F_n & F_{n-1} \end{bmatrix}$. Similarly, the Lucas $Q$-matrix, $Q_L = \begin{bmatrix}…
