Perfect monoids with zero and categories of <i>S</i>-acts
نویسندگان
چکیده
In this paper, we study the relationship between two main categories of S-acts for a monoid S with zero from viewpoint existence projective covers. particular, prove that condition all acts have cover holds in category if and only it pointed acts. Furthermore, connected are cyclic they satisfy ascending chain on subacts.

-torsion free Acts Over Monoids
In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. 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 general implies some other properties, respectively.
متن کاملOn the U-WPF Acts over Monoids
Valdis Laan in [5] introduced an extension of strong flatness which is called weak pullback flatness. In this paper we introduce a new property of acts over monoids, called U-WPF which is an extension of weak pullback flatness and give a classification of monoids by this property of their acts and also a classification of monoids when this property of acts implies others. We also show that regu...

متن کاملMöbius inversion formula for monoids with zero
The Möbius inversion formula, introduced during the 19th century in number theory, was generalized to a wide class of monoids called locally finite such as the free partially commutative, plactic and hypoplactic monoids for instance. In this contribution are developed and used some topological and algebraic notions for monoids with zero, similar to ordinary objects such as the (total) algebra o...
