On Hopfian(co-Hopfian) and Fitting S-acts (I)
Mohammad Roueentan, Roghaieh Khosravi
The main purpose of the present work is an investigation of the notions Hopfian (co-Hopfian) acts whose their surjective (injective) endomorphisms are isomorphisms. While we invest…
Chain conditions on (Rees) congruences of S-acts
Roghaieh Khosravi, Mohammad Roueentan
In this paper, we introduce (Rees) artinian S-acts as those acts that satisfy the descending chain condition on their (Rees) congruences. Then, we show that artinian S-acts are tho…
On Cogenerating and Finitely cogenerated S-acts
Roghaieh Khosravi, Xingliang Liang, Mohammad Roueentan
In this paper, cogenerating classes of -acts are introduced as those that can be used to cogenerate -acts in an appropriate sense. Next, finitely cogenerated -acts are int…
Co-uniform and hollow S-acts over monoids
Roghaieh Khosravi, Mohammad Roueentan
In this paper, we first introduce the notions of superfluous and coessential subacts. Then hollow and co-uniform S-acts are defined as the acts that all proper subacts are superflu…
