变体的Hurwitz形式是表征与变体相交于小于次多点的互补维线性空间的判别式。我们研究了Hurwitz形式的计算方面,将其与对偶变量和Chow形式联系起来,并说明了为什么Hurwitz多面体上的约简并是特殊的。
The Hurwitz form of a variety is the discriminant that characterizes linear spaces of complementary dimension which intersect the variety in fewer than degree many points. We study computational aspects of the Hurwitz form, relate this to the dual variety and Chow form, and show why reduced degenerations are special on the Hurwitz polytope.
