自旋结构与Euler类的可分性
Spin structures and the divisibility of Euler classes
摘要:
在这篇短文中,我们给出了给定两个自旋模的$KO$ -理论欧拉类整除性的几何意义。我们的动机是Furuta的10/8-不等式的封闭自旋$4$ -流形。可约项的作用在塞伯格-威滕理论的可约项方程中得到了阐明,正如唐纳森和陶贝斯在杨-米尔斯理论中所做的那样。
英文摘要:
In this short article we give a geometric meaning of the divisibility of $KO$-theoretical Euler classes for given two spin modules. We are motivated by Furuta's 10/8-inequality for a closed spin $4$-manifold. The role of the reducibles is clarified in the monopole equations of Seiberg-Witten theory, as done by Donaldson and Taubes in Yang-Mills theory.
