The Gau-Wu Number for $4 \times 4$ and Select Arrowhead Matrices

Kristin A. Camenga, Patrick X. Rault, Ilya M. Spitkovsky +1

The notion of dichotomous matrices is introduced as a natural generalization of essentially Hermitian matrices. A criterion for arrowhead matrices to be dichotomous is established,…

Singularities of Base Polynomials and Gau-Wu Numbers

Kristin A. Camenga, Louis Deaett, Patrick X. Rault +3

In 2013, Gau and Wu introduced a unitary invariant, denoted by $k (A)$ , of an $n \times n$ matrix $A$ , which counts the maximal number of orthonormal vectors $x_{j}$ such that…
