| Abstract: | Rees weakly projective property of acts and the homological classification of monoids by Rees weakly projective acts are investigated. The conditions over which Rees weakly projective property are preserved under coproducts and products. |
| |
| Keywords: | Rees weakly projective Rees factor act coproduct product |
