| Abstract: | A monoid S is called left perfect if every strongly flat left S-act is projective. The chain conditions of left and right S-acts over a left perfect monoid are discussed in this paper. Particularly Bjork Theorem of right S-act is established. |

| Keywords: | left perfect monoid projective act strongly flat act |
