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…
Angle sums on polytopes and polytopal complexes
Kristin A. Camenga
We will study the angle sums of polytopes, listed in the -vector, working to exploit the analogy between the f-vector of faces in each dimension and the alpha-vector of angle su…
Vector spaces spanned by the angle sums of polytopes
Kristin A. Camenga
In this paper, we will describe the space spanned by the angle-sums of polytopes, recorded in the alpha-vector. We will consider the angles sums of simplices and the angles sums an…
