The Bruhat decomposition of real Grassmann manifolds

File(s): https://arxiv.org/abs/1703.09276
Date: Mar 2017

Abstract: We study the Grassmann manifold Gk of all k-dimensional subspaces of Rn. The Cartan embedding Gk⊂O(n) realizes Gk as a subspace of Sln(R) and we study the decomposition inherited from the classical Bruhat decomposition. We prove that this defines a CW structure and determine the incidence numbers between cells.

This paper is not quite finished - I'm currently still looking for a more elegant description of the incidence numbers before submitting it.
