On the spectral norms of some special g-circulant matrices

摘要

In the present paper, we give upper and lower bounds for the spectral norm of g-circulant matrix, whose the first row entries are the classical Horadam numbers U-i((a,b)). In addition, we also establish an explicit formula of the spectral norm for g-circulant matrix with the first row ([U-0((a,b))](2), [U-1((a,b))](2),..., [U-n-1((a,b))](2)).
