Homological aspects of n-trivial extensions of rings

Lixin Mao

Let $R ⋉_{n} M$ be the $n$ -trivial extension of a ring $R$ by an $R$ -bimodule $M$ . We first characterize projective, injective, flat and finitely generated modules over $R\ltim…

Ding modules and dimensions over formal triangular matrix rings

Lixin Mao

Let $T = (A U 0 B)$ be a formal triangular matrix ring, where $A$ and $B$ are rings and $U$ is a $(B, A)$ -bimodule. We prove that: (1) If $U…
