In this paper, we give upper and lower bounds for the spectral norms of circulant matrices A n = Circ(F nâˆ’1) and B n = Circ(L (k,h) n and L (k,h) n are the (k, h)-Fibonacci and (k, h)-Lucas numbers,â€¦ (More)

This paper is an improving of the work from [6], in which the upper and lower bounds for the spectral norms of the matrices An = Circ(F (k,h) 0 , F (k,h) 1 , Â· Â· Â· , F (k,h) nâˆ’1 ) and Bn = Circ(Lâ€¦ (More)

Abstract In this paper, we consider the k -Fibonacci and k -Lucas sequences {Fk,n}nâˆˆN and {Lk,n}nâˆˆN . Let A = Cr(Fk,0, Fk,1, Â· Â· Â· , Fk,nâˆ’1) and B = Cr(Lk,0, Lk,1, Â· Â· Â· , Lk,nâˆ’1) be r -circulantâ€¦ (More)

In the present paper, we give upper and lower bounds for the spectral norm of g-circulant matrix, whose the rst row entries are the classical Horadam numbers U (a,b) i . In addition, we alsoâ€¦ (More)
