张量t函数:三阶张量函数的定义

The tensor t-function: a definition for functions of third-order tensors

Kathryn Lund

摘要:

给出了多维数组函数的定义。该定义适用于张量t-积形式中的三阶张量,该形式将三阶张量视为块循环矩阵。张量函数的定义具有类似的属性作为标准的矩阵函数定义的基本方案。为了证明该定义在应用中的潜力,将网络可通信性的概念推广到三阶张量,并通过矩阵函数的块Krylov子空间方法计算小规模的例子。这些方法的复杂性分析的背景下,张量。

英文摘要:

A definition for functions of multidimensional arrays is presented. The definition is valid for third-order tensors in the tensor t-product formalism, which regards third-order tensors as block circulant matrices. The tensor function definition is shown to have similar properties as standard matrix function definitions in fundamental scenarios. To demonstrate the definition's potential in applications, the notion of network communicability is generalized to third-order tensors and computed for a small-scale example via block Krylov subspace methods for matrix functions. A complexity analysis for these methods in the context of tensors is also provided.
