On gonality-tight graphs
Å imun DropuljiÄ, Yoav Len
We address a question posed by Fessler--Jensen--Kelsey--Owen regarding graphs whose second gonality is greater than the first by exactly 1. We answer the question affirmatively und…
Tropical methods for building real space sextics with totally real tritangent planes
Maria Angelica Cueto, Yoav Len, Hannah Markwig +1
This paper proposes the use of combinatorial techniques from tropical geometry to build the 120 tritangent planes to a given smooth algebraic space sextic. Although the tropical co…
The tropical Abel--Prym map
Giusi Capobianco, Yoav Len
We prove that the tropical Abel--Prym map associated with a free double cover of hyperelliptic metric…
Chip-firing games, Jacobians, and Prym varieties
Yoav Len
We present a self-contained introduction to the theory of chip-firing games on metric graphs, as well as the more recent theory of tropical Prym varieties. We briefly discuss the c…
