On properties of n-totally projective Abelian p-groups

We prove some properties of n-totally projective Abelian p-groups. Under certain additional conditions for the group structure, we obtain an equivalence between the notions of n-total projectivity and strong n-total projectivity. We also show that n-totally projective A-groups are isomorphic if they...

Description
Summary:We prove some properties of n-totally projective Abelian p-groups. Under certain additional conditions for the group structure, we obtain an equivalence between the notions of n-total projectivity and strong n-total projectivity. We also show that n-totally projective A-groups are isomorphic if they have isometric p^n-socles Доведено деякi властивостi n-тотально проекцiйних абелевих p-груп. При деяких додаткових умовах на будову груп встановлено еквiвалентнiсть понять n-тотальної проективностi та сильної n-тотальної проективностi. Також показано, що n-тотально проективнi A-групи iзоморфнi, якщо вони мають iзометричнi p^n-цоколi.
