摘要
研究环上矩阵的Гαβ-广义逆和Гαβ-Moore-Penrose逆,得到带有对合反自同构的有单位元的结合环R上的一类可分解矩阵的Гαβ-广义逆和Гαβ-Moore-Penrose逆存在的充要条件及表达式,推广了以往的相应结果。
The Гαβ-generalized inverse and Гαβ-Moore-Penrose inverse of matrices over a ring are discussed.The necessary and sufficient conditions for existence and the explicit expressions of the Гαβ-generalized inverse and Гαβ-Moore-Penrose inverse of a kind of decomposable matrices over a ring with an involution * and unitary are given,and some pre-vious results are extended.
