Structured Rectangular Tensors and Rectangular Tensor Complementarity Problems [PDF]

open access: yesMathematical Problems in Engineering, 2020
In this paper, some properties of structured rectangular tensors are presented, and the relationship among these structured rectangular tensors is also given. It is shown that all the V-singular values of rectangular P-tensors are positive. Some necessary and/or sufficient conditions for a rectangular tensor to be a rectangular P-tensor are also ...

Rectangular GLT sequences

open access: yesETNA - Electronic Transactions on Numerical Analysis, 2022
The theory of generalized locally Toeplitz (GLT) sequences is a powerful apparatus for computing the asymptotic spectral distribution of square matrices $A_n$ arising from the discretization of differential problems. Indeed, as the mesh fineness parameter $n$ increases to $\infty$, the sequence $\{A_n\}_n$ often turns out to be a GLT sequence.
