Strassen渐近秩猜想的几何方法

Towards a Geometric Approach to Strassen's Asymptotic Rank Conjecture

Austin Conner, Fulvio Gesmundo, Joseph M. Landsberg, Emanuele Ventura, Yao Wang

摘要:

首先对$\mathbb{C}^m \otimes \mathbb{C}^m \otimes \mathbb{C}^m$中的三个变种进行了几何研究(对于每个$m$),包括紧张量集合的Zaplski闭包,紧张量是具有连续正则对称性的张量。我们的动机是发展一个几何框架Strassen的渐近秩猜想,任何紧张量的渐近秩是最小的。特别是,我们确定的紧张量集的尺寸。我们证明,这个维度等于维度的一组斜张量,一个较少限制类介绍了Strassen。

英文摘要:

We make a first geometric study of three varieties in $\mathbb{C}^m \otimes \mathbb{C}^m \otimes \mathbb{C}^m$ (for each $m$), including the Zariski closure of the set of tight tensors, the tensors with continuous regular symmetry. Our motivation is to develop a geometric framework for Strassen's Asymptotic Rank Conjecture that the asymptotic rank of any tight tensor is minimal. In particular, we determine the dimension of the set of tight tensors. We prove that this dimension equals the dimension of the set of oblique tensors, a less restrictive class introduced by Strassen.
