On the norms of an $$r$$-circulant matrix with the generalized $$k$$-Horadam numbers. (English) Zbl 1373.11014
Summary: In this paper, we present new upper and lower bounds for the spectral norm of an $$r$$-circulant matrix $$H=C_r(H_{k,0}, H_{k,1}, H_{k,2},\ldots, H_{k, n-1})$$ whose entries are the generalized $$k$$-Horadam numbers. Furthermore, we obtain new formulas to calculate the eigenvalues and determinant of the matrix $$H$$.
