Abstract

We present an asymmetric qq-Painlev\'e equation. We will derive this using qq-orthogonal polynomials with respect to generalized Freud weights: their recurrence coefficients will obey this qq-Painlev\'e equation (up to a simple transformation). We will show a stable method of computing a special solution which gives the recurrence coefficients. We establish a connection with αqPV\alpha-q-P_V.
