From Eigenvalues/Eigenvectors of Hypermatrices to Canonical Form of Tensors
Daizhan Cheng, June Feng, Hongsheng Qi +1
The rings of non-square matrices based on the dimension-keeping (DK-) semi-tensor product (STP) are considered, where a virtual identity is introduced to make each ring possess an…

t-Product and t-STP of cubic matrices with an application to hyper-networked systems
Daizhan Cheng, Zhengping Ji
Control systems with tensor-valued state transitions require a product that specifies both how coefficients act on each frontal slice and how different slices interact. This paper…
