讨论与四阶对合矩阵可交换的反对合矩阵。主要结果如下:对于四阶对合矩阵A,如果A≠±I(I是单位矩阵),那么与A可交换的全体反对合矩阵可以分为四类:±iI、±iA、tr(A)=±2和tr(A)=0。
討論與四階對閤矩陣可交換的反對閤矩陣。主要結果如下:對于四階對閤矩陣A,如果A≠±I(I是單位矩陣),那麽與A可交換的全體反對閤矩陣可以分為四類:±iI、±iA、tr(A)=±2和tr(A)=0。

In this paper,we have discussed the anti-involutory matrices,which can interchange with involutory matrix. The main results are as follows:For a forth-order involutory matrix A,if A≠±I (where I is the identity matrix ),there are altogether 4 kinds of anti-involutory matrices which can interchange with A including:±iI、±iA、tr(A)=±2 and tr(A)=0.
