计算中的张量

Tensors in computations

Lek-Heng Lim

摘要:

张量的概念包含了三个伟大的思想:等变性,多重线性,可分性。但是,试图同时做三件事会让这个概念难以理解。我们将通过线性代数和数值线性代数的镜头,以一种简单易行的方式解释张量,并通过计算数学和应用数学的例子进行阐述。

英文摘要:

The notion of a tensor captures three great ideas: equivariance, multilinearity, separability. But trying to be three things at once makes the notion difficult to understand. We will explain tensors in an accessible and elementary way through the lens of linear algebra and numerical linear algebra, elucidated with examples from computational and applied mathematics.
