On the scramble number of graphs
Marino Echavarria, Max Everett, Robin Huang +3
The scramble number of a graph is an invariant recently developed to aid in the study of divisorial gonality. In this paper we prove that scramble number is NP-hard to compute, als…
The Rest of the Tilings of the Sphere by Regular Polygons
Colin Adams, Cameron Edgar, Peter Hollander +1
We determine all non-edge-to-edge tilings of the sphere by regular spherical polygons of three or more sides.
Moduli dimensions of lattice polygons
Marino Echavarria, Max Everett, Shinyu Huang +5
Given a lattice polygon with interior lattice points, we associate to it the moduli space of tropical curves of genus with Newton polygon . We completely classify th…
On finite spacer rank for words and subshifts
Su Gao, Liza Jacoby, William Johnson +4
We define a notion of rank for words and subshifts that we call spacer rank, extending the notion of rank-one symbolic shifts of Gao and Hill. We construct infinite words of each f…
Prism graphs in tropical plane curves
Liza Jacoby, Ralph Morrison, Ben Weber
Any smooth tropical plane curve contains a distinguished trivalent graph called its skeleton. In 2020 Morrison and Tewari proved that the so-called big face graphs cannot be the sk…
