The entries in the first row of A = C-r (a(0), a(1),..., a(n-1)) are a(i) = P-i, a(i) = Q(i), a(i) = P-i(2) or a(i) = Q(i)(2) (i = 0, 1, 2,..., n - 1), where P-i and Q(i) are the ith Pell and Pell-Lucas numbers, respectively. We find some bounds estimation of the spectral norm for r-Circulant matrices with Pell and Pell-Lucas numbers.en10.1186/s13660-016-0997-0info:eu-repo/semantics/openAccessPell numbersPell-Lucas numbersr-circulant matrixspectral normArticleQ2WOS:000391732400001Q2
