| Abstract: | A concept of stronger flatness was introduced by using condition(WR),then the property of stronger flatness was discussed and it was proved that all the cyclic subacts of arbitrary weakly flat right S-acts were more strongly flat if and only if S=N1,where N was a empty group or a right-zero semigroup. |
