Abstract

We investigate a Riemann-Hilbert problem (RHP), whose solution corresponds to a group of qq-orthogonal polynomials studied earlier by Ismail et al. Using RHP theory we determine new asymptotic results in the limit as the degree of the polynomials approach infinity. The RHP formulation also enables us to obtain further properties. In particular, we consider how the class of polynomials and their asymptotic behaviours change under translations of the qq-discrete lattice and determine the asymptotics of related qq-Painlev\'e equations.
