The Q0-matrix completion problem [PDF]
Arab Journal of Mathematical Sciences, 2021 A matrix is a Q0-matrix if for every k∈{1,2,…,n}, the sum of all k×k principal minors is nonnegative. In this paper, we study some necessary and sufficient conditions for a digraph to have Q0-completion. Later on we discuss the relationship between Q and

Spinning partial waves for scattering amplitudes in d dimensions
Journal of High Energy Physics, 2023 Partial wave decomposition is one of the main tools within the modern S-matrix studies. We present a method to compute partial waves for 2 → 2 scattering of spinning particles in arbitrary spacetime dimension. We identify partial waves as matrix elements

Doubly constrained totally positive line insertion
Special Matrices, 2020 It is shown that in any TP matrix, a line (row or column) with two speci˝ed entries in any positions (and the others appropriately chosen) may be inserted in any position, as long as the two entries are consistent with total positivity.
