环上一类反三角块阵的群逆
The group inverse for a class of anti-triangular block matrices over ring
摘要
设R是含1的结合环.刻画了R上一类22反三角块阵的群可逆性,并且给出了其群逆的确切表示.
Let R be an associativering with 1. Characterized the group invertibility for a class of 2 ×2 anti-triangular block matrrces and gave the explicit representations for the group inverse over R.
