相对同调代数的模型逼近

Model approximations for relative homological algebra

Simone Virili

摘要:

最近,Chachólski,Neeman,Pitsch和Scherer在一系列的三篇论文中研究了交换环上上链复形的无界范畴的模型近似。这些近似允许构造相对于特定选择的内射的内射决议。在本文中,我们定义了一般Grothendieck范畴上的上链复形的相似模型近似,推广了以前的结构,并达到更好地理解整个画面。

英文摘要:

Recently, Chachólski, Neeman, Pitsch, and Scherer studied, in a series of three papers, model approximations for the unbounded category of cochain complexes over a commutative ring. These approximations allow to construct relative injective resolutions with respect to particular choices of injectives. In this paper we define similar model approximations for cochain complexes on general Grothendieck categories generalizing the previous constructions and reaching a better understanding of the whole picture.
