Torsions of integral homology and cohomology of real Grassmannians
arXiv:1709.05623
Abstract
According to a result of Ehresmann, the torsions of integral homology of real Grassmannian are all of order $2$. In this note, We compute the $\mathbb{Z}_2$-dimensions of torsions in the integral homology and cohomology of real Grassmannian.
