It is shown that, in any semigroup with involution, both the DMP inverse of Malik and Thome [Appl Math Comp. 2014;226:575–580.] and the CMP inverse of Mehdipour and Salemi [Linear Multilinear Alg. 2018;66:1046–1053.] are special cases of the Bott–Duffin -inverse introduced in [Linear Algebra Appl. 2012;436:1909-1923.] It is also shown that the core inverse of O.M. Baksalary and Trenkler [Linear Multilinear Alg. 2010;58:681–697.] can (even for other pairs of generalized inverses) also be alternatively described, in three other equivalent ways, as the -inverse y of a for three other choices of besides .

结果表明,在任何具有对合的半群中,Malik 和 Thome [Appl Math Comp. 2014;226:575–580.] 和 Mehdipour 和 Salemi 的 CMP 逆 [线性多线性算法。2018;66:1046–1053.] 是 Bott-Duffin 的特例-inverse 在 [线性代数应用。2012;436:1909-1923.] 还显示了 OM Baksalary 和 Trenkler [线性多线性算法的核心逆。2010;58:681–697.] 也可以(即使对于其他广义逆对)也可以用其他三种等效方式替代地描述为- 对a的其他三个选择的逆y除了.
