Notes on the Sum-Rank Weight of a Matrix with Restricted Rank
Hugo Sauerbier Couvée, Hedongliang Liu · 2023-11-17 · via cs.IT updates on arXiv.org

These notes cover a few calculations regarding the sum-rank weight of a matrix in relation to its rank. In particular, a formula and lower bounds are given on the probability that a matrix of rank $t$ consisting of $\ell$ blocks has sum-rank weight $\ell t$.
