Some new bounds for the Hadamard product and the Fan product of matrices

Qian-Ping Guo, Hou-Biao Li, Jin-Song Leng

If $A$ and $B$ are nonnegative matrices, a sharp upper bound on the spectral radius $ρ (A \circ B)$ for the Hadamard product of two nonnegative matrices is given, and the minimum eig…

A note on the growth factor in Gaussian elimination for Higham matrices

Qian-Ping Guo, Xian-Ming Gu, Hou-biao Li

The Higham matrix is a complex symmetric matrix A=B+iC, where both B and C are real, symmetric and positive definite and $i = - 1$ is the imaginary unit. For any Higha…
