一类Moore-Penrose逆的存在性
The Existence of A Tyge of Moore-Penrose Inverses
【摘要】 研究了范畴中具有泛分解的态射f关于对称态射β、γ的加权Moore-Penrose逆f+β,γ,给出了其存在的充要条件和相应的表达式.
【Abstract】 In this paper,the weighted Moore-Penrose inverses of morphisms with universal-factorization in the category are studied,and some necessary and sufficient conditions for existences and their previous expressions are given.
