论文摘要
我们计算了贝林森 - 德林菲尔德(Beilinson-Drinfeld)亲戚格拉斯曼尼亚人(Grassmannians)的球形舒伯特(Schubert subvarieties)的决定符号束的权力部分的空间。答案是根据当前谎言代数的全球纽扣模块给出的。
We compute the spaces of sections of powers of the determinant line bundle on the spherical Schubert subvarieties of the Beilinson- Drinfeld affine Grassmannians. The answer is given in terms of global Demazure modules over the current Lie algebra.
