The Spark of Symmetric Matrices Described by a Graph

Louis Deaett, Shaun Fallat, Veronika Furst +3

We investigate the sparsity of null vectors of real symmetric matrices whose off-diagonal pattern of zero and nonzero entries is described by the adjacencies of a graph. We use the…

Fixed point groups of involutions of type $O (q, k)$ over a field of characteristic two

Mark Hunnell, John Hutchens

For $O (q, k)$ , the orthogonal group over a field $k$ of characteristic 2 with respect to a quadratic form $q$ , we discuss the isomorphism classes of fixed…

Involutions of type $G_{2}$ over a field of characteristic 2

John Hutchens, Nathaniel Schwartz

In this paper we give a classification of classes of involutions on an automorphism group of an octonion algebra over fields of characteristic 2, and describe the classes of their…
