关于最大秩、典型秩和一般秩

On Maximum, Typical and Generic Ranks

Grigoriy Blekherman, Zach Teitler

摘要:

我们表明,对于几个概念的秩,包括张量秩,华林秩,广义秩相对于一个射影簇,秩的最大值是最多两倍的一般秩。我们证明了在实数上,实秩的最大值至多是最小典型秩的两倍,这等于(复)一般秩。

英文摘要:

We show that for several notions of rank including tensor rank, Waring rank, and generalized rank with respect to a projective variety, the maximum value of rank is at most twice the generic rank. We show that over the real numbers, the maximum value of the real rank is at most twice the smallest typical rank, which is equal to the (complex) generic rank.
