Refined curve counting with descendants and quantum mirrors

Abstract

Given a log Calabi--Yau surface (Y,D)(Y,D), Bousseau has constructed a quantization of the mirror algebra of this pair. We give a formula for structure constants of this quantization in terms of higher genus descendant logarithmic Gromov--Witten invariants of (Y,D)(Y,D). Our result generalises the weak Frobenius structure conjecture for surfaces to the qq-refined setting, and is proved by relating these invariants to counts of quantum broken lines in the associated quantum scattering diagram.
