The $\varphi$-conjugation of quaternionic matrices and generalized Autonne-Takagi factorization

Cailing Yao, Bingzhe Hou, Yue Xin

Let $\varphi$ be a quaternion of modulus $1$. In this article, we study some topics related to $\varphi$-conjugation for quaternionic matrices, including $\varphi$-Hermitian matrices, $\varphi$-conjugate…
