Proof of Two Multivariate -Binomial Sums Arising in Gromov-Witten Theory

We prove two multivariate -binomial identities conjectured by Bousseau, Brini, and van Garrel [Geom. Topol. 28 (2024), 393-496, arXiv:2011.08830], which give generating series for Gromov-Witten invariants of two specific log Calabi-Yau surfaces. The key identity in all the proofs is Jackson's -...

I am indebted to the anonymous referees for their many extremely helpful comments, which not only led to an improved presentation but also let me discover a subtle gap in the proof of Proposition 3 in the original version of the manuscript. This research was partially supported by the Austrian Science Foundation FWF (grant S50-N15) in the framework of the Special Research Program “Algorithmic and Enumerative Combinatorics”.
