$(\mathcal{F},\mathcal{A})$ -Gorenstein平坦同调维数

$(\mathcal{F},\mathcal{A})$-Gorenstein flat homological dimensions

Víctor Becerril

摘要:

本文研究了Gillespie提出的$(\mathcal{L}, \mathcal{A})$ -Gorenstein平坦$R$ -模$\mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$的同调性质.其中类$\mathcal{A} \subseteq \mathrm{Mod} (R^{op})$有时对应于对偶对$(\mathcal{L}, \mathcal{A})$。研究了$\mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$的弱整体维数和有限维数,证明了在$(\mathcal{L}, \mathcal{A})$ -Gorenstein环上,函子$-\otimes _R -$在$\mathrm{Mod} (R^{op}) \times \mathrm{Mod} (R)$上被类$\mathcal{GF}_{(\mathcal{F}(R^{op}), \mathcal{A})} \times \mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$左平衡.当对偶对为$(\mathcal{F} (R), \mathcal{FP}Inj (R^{op}))$时,我们恢复了G.杨的结果在丁陈环,我们看到,这是新的$(\mathrm{Lev} (R), \mathrm{AC} (R^{op}))$等。

英文摘要:

In this paper we develop the homological properties of the $(\mathcal{L}, \mathcal{A})$-Gorenstein flat $R$-modules $\mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$ proposed by Gillespie. Where the class $\mathcal{A} \subseteq \mathrm{Mod} (R^{op})$ sometimes corresponds to a duality pair $(\mathcal{L}, \mathcal{A})$. We study the weak global and finitistic dimensions that comes with $\mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$ and show that over a $(\mathcal{L}, \mathcal{A})$-Gorenstein ring, the functor $-\otimes _R -$ is left balanced over $\mathrm{Mod} (R^{op}) \times \mathrm{Mod} (R)$ by the classes $\mathcal{GF}_{(\mathcal{F}(R^{op}), \mathcal{A})} \times \mathcal{GF}_{(\mathcal{F}(R), \mathcal{A})}$. When the duality pair is $(\mathcal{F} (R), \mathcal{FP}Inj (R^{op}))$ we recover the G. Yang's result over a Ding-Chen ring, and we see that is new for $(\mathrm{Lev} (R), \mathrm{AC} (R^{op}))$ among others.
