Refined Tropical Invariants and Characteristic Numbers (Uriel Sinichkin, Tel-Aviv University)

05.02.2025 14:00 – 16:00

Abstract:
In this talk I will present a generalization of Goettche-Schroeter and Schroeter-Shustin refined counts of tropical curves that splits to a product of terms on small fragments of the curves. This count is invariant in each of the following situations: either genus at most one, or a single contact element, or point conditions in Mikhalkin position. I will compare our results to Mével’s floor diagram approach, and discuss the specialization of the count at q=1, which recovers certain characteristic numbers.
