Spin structures of flat manifolds of diagonal type
arXiv:1602.08585 · doi:10.4310/HHA.2019.v21.n2.a18
Abstract
For each integer at least two, we construct non-spin closed oriented flat manifolds with holonomy group and with the property that all of their finite proper covers have a spin structure. Moreover, all such covers have trivial Stiefel-Whitney classes.
