Each n-by-n matrix with n>1 is a sum of 5 coninvolutory matrices

Ma. Nerissa M. Abara, Dennis I. Merino, Vyacheslav I. Rabanovich +2

An $n \times n$ complex matrix $A$ is called coninvolutory if $A ˉ A = I_{n}$ and skew-coninvolutory if $A ˉ A = - I_{n}$ (which implies that $n$ is even). We prove that each matrix of s…

Littlewood's algorithm and quaternion matrices

Dennis I. Merino, Vladimir V. Sergeichuk

A strengthened form of Schur's triangularization theorem is given for quaternion matrices with real spectrum (for complex matrices it was given by Littlewood). Littlewood's algorit…
