K[x,y,z]中线性型的弱Lefschetz性质和幂

The Weak Lefschetz Property and powers of linear forms in K[x,y,z]

Hal Schenck, Alexandra Seceleanu

摘要:

本文证明了K[x,y,z]与由线性型的幂生成的理想I的Artin商具有弱Lefschetz性质.如果I的合合丛是半稳定的,这是从布伦纳-凯德的结果得出的;我们的证明在没有这个假设的情况下也能工作,而这个假设通常是不成立的。

英文摘要:

We show that an Artinian quotient of K[x, y, z] by an ideal I generated by powers of linear forms has the Weak Lefschetz property. If the syzygy bundle of I is semistable this follows from results of Brenner-Kaid; our proof works without this hypothesis, which typically does not hold.
