A monoid S satisfies Condition (A) if every locally cyclic left S-act is cyclic. This condition first arose in Isbell’s work on left perfect monoids, that is, monoids such that every left S-act has a projective cover. Isbell showed that S is left perfect if and only if every cyclic left S-act has a projective cover and Condition (A) holds. Fountain built on Isbell’s work to show that S is left ...

The investigation of equational compactness was initiated by Banaschewski and Nelson. They proved that pure injectivity is equivalent to equational compactness. Here we define the so called sequentially compact acts over semigroups and study some of their categorical and homological properties. Some Baer conditions for injectivity of S-acts are also presented.
D e f i n i t i o n 6. Let T = (S, R, L, Act, so) be an LTS. A function h : S -4 S is a selection function if and only if there exists a bisimulation relation B C S • S between T and T such that; For all s e S , 8 h(8) s B s' implies that h(s) = h(s') We say that h preserves the bisimulation relation B. Intuitively, the function h picks a representative from each equivalence class of S induced ...
