Higher-distance commuting varieties
Madeleine Elyze, Alexander Guterman, Ralph Morrison +1
The commuting variety of matrices over a given field is a well-studied object in linear algebra and algebraic geometry. As a set, it consists of all pairs of square matrices with e…
Graphs of gonality three
Ivan Aidun, Frances Dean, Ralph Morrison +2
In 2013, Chan classified all metric hyperelliptic graphs, proving that divisorial gonality and geometric gonality are equivalent in the hyperelliptic case. We show that such a clas…
Treewidth and gonality of glued grid graphs
Ivan Aidun, Frances Dean, Ralph Morrison +2
We compute the treewidth of a family of graphs we refer to as the glued grids, consisting of the stacked prism graphs and the toroidal grids. Our main technique is constructing str…
