| Abstract: | In this paper, the concepts of weakly short splitting exact sequences which are generalized from splits are introduced. The characterizations of weak splits are also studied. Finally, the author proves a proposition about an equivalent condition of flat modules applying with left weak splitting. |
| Keywords: | short exact sequences splits weak splitting |
