Floor diagrams and refined invariants in positive genus
Abstract
Göttche-Schroeter invariants are a rational tropical refined invariant, i.e. a
polynomial counting genus 0 curves on toric surfaces. In this talk I will use a floor
diagrams approach to extend these invariants in any genus. I will then say few words
on the link between this new quantity and the one simultaneously defined by Shustin
and Sinichkin.
