摘要
从代数的角度出发,分别给出了基于{2}-逆的三种广义逆:{2,3}-逆,{2,4}-逆以及{2,3,4}-逆,得到了代数上的各种构造和一些几何特性,从而补充了对广义逆的研究.
From the viewpoint of algebra, three generalized inverses based on inverse are studied in this paper. The three generalized inverses are ： { 2,3 }-inverse, { 2,4 } inverse and {2, 3, 4}-inverse. The paper shows their some geometric properties and algebraic constructions, complementing the research of generalized inverses.
