超平面排列的跳跃数

Jumping numbers of hyperplane arrangements

Nero Budur

摘要:

M.齐藤最近证明了超平面排列的跳跃数只取决于排列的组合学。然而,仍然缺少一个关于组合数据的公式。本文给出了超平面排列的跳跃数只与组合学有关的一个公式和另一种证明。我们还给出了部分Hodge谱和内部跳跃多重数的组合公式。

英文摘要:

M. Saito recently proved that the jumping numbers of a hyperplane arrangement depend only on the combinatorics of the arrangement. However, a formula in terms of the combinatorial data was still missing. In this note, we give a formula and a different proof of the fact that the jumping numbers of a hyperplane arrangement depend only on the combinatorics. We also give a combinatorial formula for part of the Hodge spectrum and for the inner jumping multiplicities.
