Tropical curves in abelian surfaces I: enumeration of curves passing through points (2202.07250v2)

Abstract: This paper is the first part in a series of three papers devoted to the study of enumerative invariants of abelian surfaces through the tropical approach. In this paper, we consider the enumeration of genus $g$ curves of fixed degree passing through $g$ points. We compute the multiplicity provided by a correspondence theorem due to T. Nishinou and show that it is possible to refine this multiplicity in the style of Block-G\"ottsche to get tropical refined invariants.
