Chip-Firing on Trees of Loops
Keywords: Chip-firing, Metric graphs, Brill-Noether generality
AbstractCools, Draisma, Payne, and Robeva proved that generic metric graphs that are "paths of loops" are Brill-Noether general. We show that Brill-Noether generality does not hold for "trees of loops": the only trees of loops that are Brill-Noether general are paths of loops. We study various notions of generality and examine which of these graphs satisfy them.
