Strongly $ϕ$ -flat modules, strongly nonnil-injective modules and their homological dimensions

Xiaolei Zhang, Shiqi Xing, Wei Qi

In this paper, we first introduce and study the notions of strongly $ϕ$ -flat modules and strongly nonnil-injective modules. And then, we investigate the homology dimensions of modu…

Two generalizations of Krull domains

Shiqi Xing, Daniel D. Anderson, Muhammad Zafrullah

In this paper we introduce two new generalizations of Krull domains: $*$ -almost independent rings of Krull type ( $*$ -almost IRKTs) and $*$ -almost generalized Krull domains…

Almost discrete valuation domains

Daniel D. Anderson, Shiqi Xing, Muhammad Zafrullah

Let $D$ be an integral domain. Then $D$ is an almost valuation (AV-)domain if for $a, b \in D ∖ {0}$ there exists a natural number $n$ with $a^{n} ∣ b^{n}$ or $b^{n}\mid…

On $L_{n}$ -Injective Modules and $L_{n}$ -Injective Dimensions

Tao Xiong, Fanggui Wang, Lei Qiao +2

Let $R$ be a ring, and $n$ a fixed nonnegative integer. An $R$ -module $W$ is called $L_{n}$ -injective if $Ext_{R}^{1} (M, W) = 0$ for any $R$ -module $M$ with flat dimension at mo…
