Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in generalĀ  implies some other properties, respectively.}, keywords = {-torsion free,Rees factor act,cyclic act}, url = {https://jsciences.ut.ac.ir/article_35644.html}, eprint = {https://jsciences.ut.ac.ir/article_35644_4421edc61d552666080fed1b8a86eeac.pdf} }
