Özet
The aim of this paper is to investigate quasi-corational, comonoform, copolyform and alpha-(co)atomic modules. It is proved that for an ordinal ct a right R-module M is alpha -atomic if and only if it is alpha -coatomic. And it is also shown that an ct-atomic module M is quasi-projective if and only if M is quasi-corationally complete. Some other results are developed.
