摘要
Arne Strom在其题为“同伦范畴是一个同伦范畴”的论文中,证明了拓扑空间的范畴顶满足Quillen意义上的抽象同伦范畴公理。在本研究中,我们通过实例表明,Quillen在Top上的模型结构未能捕捉到经典同伦理论的一些微妙之处,并且我们也表明,不能从Quillen的公理化方法中检索到整个经典同伦理论。因此,我们证明了模型范畴是经典同伦理论的不完全模型。
A Note on “The Homotopy Category is a Homotopy Category”
In his paper with the title, “The Homotopy Category is a Homotopy Category”, Arne Strom shows that the category Top of topo- logical spaces satisfies the axioms of an abstract homotopy category in the sense of Quillen. In this study, we show by examples that Quillen’s model structure on Top fails to capture some of the subtleties of classical homotopy theory and also, we show that the whole of classical homo-topy theory cannot be retrieved from the axiomatic approach of Quillen. Thus, we show that model category is an incomplete model of classical homotopy theory.
