遗传Abel模型范畴的典范归结

Canonical resolutions in hereditary abelian model categories

James Gillespie

摘要:

任何阿贝尔模型范畴的每个对象都有一个规范解析,如本文所述。当模型结构是遗传的,我们展示了如何在相关同伦范畴的态射集可以实现为从这些决议计算的上同调群。我们还给出了另一种描述的态射集的米田Ext组。

英文摘要:

Each object of any abelian model category has a canonical resolution as described in this article. When the model structure is hereditary we show how morphism sets in the associated homotopy category may be realized as cohomology groups computed from these resolutions. We also give an alternative description of the morphism sets in terms of Yoneda Ext groups.
