On the Geometry of Numerical Ranges Over Finite Fields
Kristin A. Camenga, Brandon Collins, Gage Hoefer +4
Numerical ranges over a certain family of finite fields were classified in 2016 by a team including our fifth author. Soon afterward, in 2017 Ballico generalized these results to a…
The Gau-Wu Number for 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 , of an matrix , which counts the maximal number of orthonormal vectors such that…
Absolutely Flat Idempotents
Jonathan M. Groves, Yonatan Harel, Christopher J. Hillar +2
A real -by- idempotent matrix with all entries having the same absolute value is called {\it absolutely flat}. We consider the possible ranks of such matrices and herein…
