Some Bounds for the spectral norms of geometric and r-circulant matrices
with generalized Jacobsthal-Lucas numbers
Abstract
The purpose of this paper is to investigate the bounds of the spectral
norms of r-circulant and geometric circulant matrices whose
elements are a generalization of Jacobsthal-Lucas numbers called
bi-periodic Jacobsthal-Lucas numbers by three different ways. We also
present the sum of entries; the maximum column sum matrix norm and the
maximum row sum matrix norm of this circulant matrices. Then, we present
bounds for the spectral norms of Kronecker and Hadamard products of
r-circulant matrices and geometric circulant matrices with
bi-periodic Jacobsthal-Lucas numbers. Finally, we give an explicit
formula for the eigenvalues of r-circulant matrix with the
bi-periodic Jacobsthal-Lucas numbers.
