Tropical Methods in Hurwitz-Brill-Noether Theory
Kaelin Cook-Powell, David Jensen
Splitting type loci are the natural generalizations of Brill-Noether varieties for curves with a distinguished map to the projective line. We give a tropical proof of a theorem of…
A New Lower Bound on Graph Gonality
Michael Harp, Elijah Jackson, David Jensen +1
We define a new graph invariant called the scramble number. We show that the scramble number of a graph is a lower bound for the gonality and an upper bound for the treewidth. Unli…
The Kodaira dimensions of and
Gavril Farkas, David Jensen, Sam Payne
We prove that the moduli spaces of curves of genus 22 and 23 are of general type. To do this, we calculate certain virtual divisor classes of small slope associated to linear serie…
Scrollar Invariants of Tropical Curves
David Jensen, Kalila Lehmann
We define scrollar invariants of tropical curves with a fixed divisor of rank 1. We examine the behavior of scrollar invariants under specialization, and provide an algorithm for c…
