Uniformly $S$ -Noetherian rings

Wei Qi, Hwankoo Kim, Fanggui Wang +2

Let $R$ be a ring and $S$ a multiplicative subset of $R$ . Then $R$ is called a uniformly $S$ -Noetherian ( $u$ - $S$ -Noetherian for abbreviation) ring provided there exists an element…

Metamagnetic Transitions in Few-Layer CrOCl Controlled by Magnetic Anisotropy Flipping

Minjie Zhang, Qifeng Hu, Chenqiang Hua +10

The pivotal role of magnetic anisotropy in stabilising two-dimensional (2D) magnetism has been widely accepted, however, direct correlation between magnetic anisotropy and long-ran…

The small finitistic dimensions of commutative rings

Xiaolei Zhang, Fanggui Wang

Let $R$ be a commutative ring with identity. The small finitistic dimension $\fPD(R)$ of $R$ is defined to be the supremum of projective dimensions of $R$ -modules with finite proje…

A new version of a theorem of Kaplansky

Fanggui Wang, Lei Qiao

A well-known theorem of Kaplansky states that any projective module is a direct sum of countably generated modules. In this paper, we prove the $w$ -version of this theorem, where $…

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…

Super finitely presented modules and Gorenstein projective modules

Fanggui Wang, Lei Qiao, Hwankoo Kim

Let $R$ be a commutative ring. An $R$ -module $M$ is said to be super finitely presented if there is an exact sequence of $R$ -modules $\cdots\rightarrow P_n\rightarrow\cdots \righta…
