线性系的基轨迹与Waring问题

Base loci of linear systems and the Waring problem

M. Mella

摘要:

针对一类线性型的Waring问题,要求将一个$f$型分解为若干个线性型的幂.一个经典的问题是确定何时这样的分解是唯一的。在这篇笔记中,我改进了arXiv:math/0406288 v1中的工作,并在整除性假设下回答了这个问题。为了做到这一点,我翻译成一个几何的代数语句有关的线性系的$P^n$与指定的奇异的基本轨迹。

英文摘要:

Waring problem for homogeneus forms asks for additive decomposition of a form $f$ into powers of linear forms. A classical problem is to determine when such a decomposition is unique. In this note I refine the work in arXiv:math/0406288v1 and answer this question under a divisibility assumption. To do this I translate the algebraic statement into a geometric one concerning the base loci of linear systems of $P^n$ with assigned singularities.
