我们将扭仿射格拉斯曼空间中的Schubert簇的几何与对称空间中的幂零簇联系起来。这推广了Achar-Henderson在扭曲情形下的一些结果。我们还得到了某些经典对称空间中2阶幂零簇几何的一些应用。
We relate the geometry of Schubert varieties in twisted affine Grassmannian and the nilpotent varieties in symmetric spaces. This extends some results of Achar–Henderson in the twisted setting. We also get some applications to the geometry of the order 2 nilpotent varieties in certain classical symmetric spaces.
