Low T-Phase Rank Approximation of Third Order Tensors

Taehyeong Kim, Hayoung Choi, Yimin Wei

We study low T-phase-rank approximation of sectorial third-order tensors $A \in C^{n \times n \times p}$ under the tensor T-product. We introduce canonical T-phases…

$M$ -QR decomposition and hyperpower iterative methods for computing outer inverses of tensors

Ratikanta Behera, Krushnachandra Panigrahy, Jajati Keshari Sahoo +1

The outer inverse of tensors plays increasingly significant roles in computational mathematics, numerical analysis, and other generalized inverses of tensors. In this paper, we com…
