Từ khóa:
Nilpotent-coinvariant; projective cover; X-(pre)coverTóm tắt
A module is called nilpotent-coinvariant if it is invariant under any nilpotent endomorphism of its projective cover. Some properties of this class of these modules were investigated by Truong Cong Quynh, Adel Abyzov, Dinh Duc Tai [8]. In this paper, we continue to study nilpotent-coinvariant modules over general covers.
