纯投射模的无圈复形的同伦范畴

The homotopy category of acyclic complexes of pure-projective modules

James Gillespie

摘要:

设$R$是任何具有单位元的幺环。证明了纯投射$R$ -模的所有非循环链复形的同伦范畴是一个复生成的三角范畴。我们这样做,通过构建阿贝尔模型结构,把这个同伦范畴到一个与其他两个compensarily生成的三角范畴:通常导出范畴的$R$和纯导出范畴的$R$。这也为导出范畴提供了一个新的模型。

英文摘要:

Let $R$ be any ring with identity. We show that the homotopy category of all acyclic chain complexes of pure-projective $R$-modules is a compactly generated triangulated category. We do this by constructing abelian model structures that put this homotopy category into a recollement with two other compactly generated triangulated categories: The usual derived category of $R$ and the pure derived category of $R$. This also gives a new model for the derived category.
