| Abstract: |
| In this paper, the weighted (i, …, j) inverses of morphisms with universal-factorization in the preadditive category are studied, and some new necessary and sufficient conditions for existences and expressions of it are given.Some previous results on the generalized (i, …, j) inverses of morphisms with universal-factorization are extended. |
| Key words: preadditive category morphism weighted (i, …, j) inverse |
