| Mar 12, 2013 at 19:16 | comment | added | David Treumann | I have nothing against Schubert cells, but the attaching maps are very complicated. I would be just as interested in hearing about a regular cell complex structure as a triangulation, but it's easy to get from one to the other so I asked about triangulations. If you know a triangulation that refines the Schubert stratification, so much the better! | |

Is there a particular reason why you want a triangulation? The Schubert cells are PLCW complexes so you could in principle refine these in perhaps some canonical way to get a nice triangulation. | |
