Positivity of GCD tensors and their determinants

Projesh Nath Choudhury, Krushnachandra Panigrahy

Let $S = {s_{1}, s_{2}, \dots, s_{n}}$ be an ordered set of $n$ distinct positive integers. The $m$ th-order $n$ -dimensional tensor $T_{[S]} = (t_{i_{1} i_{2} \dots i_{m}}),$ where $t_{i…

$M$ -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…
