On the piecewise quasipolynomiality of double tropical Welschinger invariants
Vincenzo Reda
Ardila and Brugallé conjectured that double tropical Welschinger invariants of Hirzebruch surfaces are piecewise quasipolynomial. In this work, we prove the conjecture holds in fu…

Universal piecewise polynomiality for counting curves in toric surfaces
Marvin Anas Hahn, Vincenzo Reda
Inspired by piecewise polynomiality results of double Hurwitz numbers, Ardila and Brugallé introduced an enumerative problem which they call double Gromov--Witten invariants of Hi…
