m-满理想和分支线性理想的弱Lefschetz性质

The weak Lefschetz property for m-full ideals and componentwise linear ideals

Tadahito Harima, Junzo Watanabe

摘要:

本文给出了m-满理想定义的标准分次Artin环具有弱Lefschetz性质的一个充要条件,该条件是分次贝蒂数表示的.这是Wiebe关于分量线性理想的一个定理的推广。我们还证明了分支线性理想类和完全m-满理想类在特征零和正特征上是一致的。分级反序字典序是稳定的。

英文摘要:

We give a necessary and sufficient condition for a standard graded Artinian ring defined by an m-full ideal, to have the weak Lefschetz property in terms of graded Betti numbers. This is a generalization of a theorem of Wiebe for componentwise linear ideals. We also prove that the class of componentwise linear ideals and that of completely m-full ideals coincide in characteristic zero and in positive characteristic, with the assumption that the generic initial ideal w.r.t. the graded reverse lexicographic order is stable.
