| Dec 27, 2011 at 23:28 | comment | added | Ruke | I'm certain this can be done in theory, but I want to know if there is an easy/fast way to do this? Once I found the class of $V$, I would intersect with other classes to get numbers. It does not matter what basis one uses, as long as it is fast/easy. | |

| Dec 27, 2011 at 21:12 | comment | added | Alexander Woo | Let me try to rephrase. You have a subvariety $V$ of the Grassmannian $G_{k,n}$, and you know $[V][W]\in H^*(G_{k,n})$ whenever $W$ is such that $[V][W]$ is a multiple of the class of a point (i.e. the top dimensional class). You want to know $[V]\in H^*(G_{k,n})$ (presumably either in terms of Schubert classes or in terms of the (anti)tautological line bundles). Correct? | |
