Change-of-Rings Theorems for the Small Finitistic Dimension

Tao Xiong, Younes El Haddaoui, Hwankoo Kim +1

In this paper, we study the small finitistic dimension of a commutative ring from the viewpoint of finitistic flat homological algebra. Using the class $F P R (R)$ of modules admittin…

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…
