The spectral norm of a Horadam circulant matrix

Abstract

Let $a$, $b$, $p$, $q$ be integers and~$(h_n)$ defined by $h_0=a$, $h_1=b$, $h_n=p{h}_{n-1}+q{h}_{n-2}$, $n=2,3,\dots$. Complementing to certain previously known results, we study the spectral norm of the circulant matrix corresponding to $h_0,\dots ,h_{n-1}$.
