Floor diagrams and some tropical invariants in positive genus (Gurvan Mével, UNIGE)

19.02.2025 14:00 – 16:00

Abstract:
Göttche-Schroeter invariants are a rational tropical refined
invariant, i.e. a polynomial counting genus 0 curves on toric surfaces,
that can be computed with a floor diagrams approach. In this talk I will
explain that this approach extends in any genus. This gives new
invariants, related to ones simultaneously defined by Shustin and
Sinichkin. I will then say few words on a quadratically enriched (and
not refined !) version of this extension.
