Logarithmic Picard groups, chip firing, and the combinatorial rank
Tyler Foster, Dhruv Ranganathan, Mattia Talpo +1
Illusie has suggested that one should think of the classifying group of -torsors on a logarithmically smooth curve over a standard logarithmic point as a logarithmic…
Skeletons of stable maps II: Superabundant geometries
Dhruv Ranganathan
We implement new techniques involving Artin fans to study the realizability of tropical stable maps in superabundant combinatorial types. Our approach is to understand the skeleton…
A note on Brill--Noether existence for graphs of low genus
Stanislav Atanasov, Dhruv Ranganathan
In an influential 2008 paper, Baker proposed a number of conjectures relating the divisor theory of algebraic curves with an analogous combinatorial theory on finite graphs. In thi…
A graphical interface for the Gromov--Witten theory of curves
Renzo Cavalieri, Paul Johnson, Hannah Markwig +1
We explore the explicit relationship between the descendant Gromov--Witten theory of target curves, operators on Fock spaces, and tropical curve counting. We prove a classical/trop…
