AI 中文摘要
在这项工作中,我们采用拓扑方法,引入了极大环面作用于\(\operatorname{Gr}(2,\mathbb{C}^{5})\)的轨道空间的同伦模型。利用此同伦模型,我们计算了整同调群并研究了轨道空间的同伦型。更确切地说,我们赋予该同伦模型一个包含一个顶胞腔的CW复形,并确定轨道空间顶胞腔附着映射的同伦类。
英文摘要
In this work, we take a topological approach and introduce a homotopy model of the orbit space of a maximal torus action on $\operatorname{Gr}(2, \mathbb{C}^{5})$. Using this homotopy model, we compute the integral homology groups and study the homotopy type of the orbit space. More precisely, we endow the homotopy model with a CW complex that contains one top cell and determine the homotopy class of the attaching map of the top cell of the orbit space.
