In addition, we found lower and upper bounds for the spectral norms and Euclidean norms of Hilbert matrix, its Hadamard square root, Cauchy-Toeplitz and Cauchy-Hankel matrices in the forms H = (1/(i + j - 1))(i, j=1)(n), H degrees(1/2) = (1/(i + j - 1)(1/2))(i, j=1)(n), T-n = [1/(g + (i - j)h)](i, j=1)(n), and H-n = [1/(g + (i + j)h)](i,j=1)(n), respectively.eninfo:eu-repo/semantics/closedAccessHilbert matrixCauchy-Toeplitz matrixCauchy-Hankel matrixNormLower and Upper boundsArticle110249264Q4WOS:000322091300025Q4
