Abstract: By introducing the notion of cyclic pure phantom morphisms, we gave some equivalent characterizations of cyclic pure phantom morphisms, proved that every R-module had an epic cyclic pure phantom cover with the kernel cyclic pure injective modules, and discussed the transitivity of cyclic pure phantom precover under change of rings.
Key words: cyclic pure, cyclic pure phantom morphism, precover
