Refined count of rational tropical curves in arbitrary dimension
Abstract
In this talk we will introduce a refined multiplicity for rational tropical curves in
any dimension. This multiplicity generalizes the multiplicity of Block-Göttsche for
planar tropical curves. We also show that the count of solutions to some general
tropical enumerative problem using this new multiplicity leads tropical refined
invariants, hinting toward the existence of classical refined invariants for classical
rational curves.
