Abstract

This work investigates the qq-deformation of (r,s)(r,s)-Airy structures and their realization via qq-difference operators, providing a bridge between quantum spectral curves and integrable systems. We construct an all-order qq-WKB solution for the matrix systems associated with the qq-quantized curve Eq(x,y)=0E_q(x,y)=0. We demonstrate that the resulting non-perturbative connected qq-amplitudes satisfy a set of shifted qq-loop equations, which can be interpreted as the Ward identities of a qq-deformed W(glr)\mathcal{W}(\mathfrak{gl}_r) algebra. Our main result provides a rigorous classification of admissible (r,s,q)(r,s,q) pairs and qq-Casimir configurations that satisfy the qq-topological type property. This ensures that the semi-classical expansion is uniquely governed by the qq-topological recursion, offering new insights into the qq-quantization of mirror curves and their underlying algebraic structures.
