摘要: 研究了弱投射系的性质,讨论了弱投射系关于余直积和直积封闭的条件,并考虑了弱投射性关于Rees短正合序列的传递性。

关键词: 弱投射, 余直积, 直积, Rees短正合序列

Abstract: Weakly projective property of acts is investigated, the conditions that preserve weakly projective property under coproducts and products are discussed, and transitivity of weakly projective property on Rees short exact sequences is also considered.

Key words: weakly projective, coproduct, product, Rees short exact sequence
