本文证明了Schubert簇在极小G/P中的退化,以及旗形簇SL(n)/B中的Kempf簇类退化为(正常)环面簇.因此,我们得到行列式变元退化为(正规)复曲面变元。
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties. As a consequence, we obtain that determinantal varietes degenerate to (normal) toric varieties.
