Abstract |
|
We give a new proof to V. B. Mehta and A. Ramanthan’s theorem that the Schubert subschemes in a flag scheme are all simultaneously compatibly split, using the representation theory of infinitesimal algebraic groups. In particular, the present proof dispenses with the Bott-Samelson schemes. |
