چکیده
|
In this paper, we give a necessary and sufficient condition for cyclic act to have a (pf′′)-cover and give some classes of monoids that all cyclic right s-acts have a condition (pf′′)-cover. ##we show that every weakly pullback flat cover is also (pf′′)-cover and every (pf′′)-cover is (p′)- cover, but the converses are not true.
