(Lack图范畴的模型结构

(Lack of) Model Structures on the Category of Graphs

Shuchita Goyal, Rekha Santhanam

摘要:

本文研究了以$\times$ -同伦等价为弱等价的有限图范畴上的模型结构。我们表明,不存在类似的Strøm-Hurewicz模型结构的这一类图。更有趣的是,我们表明,这类图与$\times$ -同伦等价不具有模型结构时,类cofibrations是一个子类的图包含。

英文摘要:

In this article, we study model structures on the category of finite graphs with $\times$-homotopy equivalences as the weak equivalences. We show that there does not exist an analogue of Strøm-Hurewicz model structure on this category of graphs. More interestingly, we show that this category of graphs with $\times$-homotopy equivalences does not have a model structure whenever the class of cofibrations is a subclass of graph inclusions.
