SUMMARY:An algebraic interpretation of the combinatorial rank of divisors
DESCRIPTION:Speaker: Yoav Len\, Yale University\n\nIn tropical geometry, one often studies nodal curves by considering combinatorial invariants of their dual graph. For instance, a line bundle on the curve gives rise to a divisor on the dual graph, which, in analogy with divisors on curves, has an invariant called the rank. \\ A conjecture by Lucia …
