Injectivity of modules over trusses

Yongduo Wang, Shujuan Han, Dengke Jia +2

As the dual notion of projective modules over trusses, injective modules over trusses are introduced. The Schanuel Lemmas on projective and injective modules over trusses are exhib…

Several results on exact sequences in categories of modules over trusses

Yongduo Wang, Dengke Jia, Jian He +1

Categorical aspects of the theory of modules over trusses were studied in recent years. The snake lemma and the nine lemma in categories of modules over trusses are formulated in t…

Characterizations of I-semiregular and I-semiperfect rings

Yongduo Wang

Let $M$ be a left module over a ring $R$ and $I$ an ideal of $R$ . We call $(P, f)$ a (locally)projective $I$ -cover of $M$ if $f$ is an epimorphism from $P$ to $M$ , $P$ is (locally)…
