@article{Witte2012ConstructionOA, title={Construction of a Lax Pair for the E6(1)q-Painlev{\'e} System}, author={Nicholas S. Witte and Christopher M. Ormerod}, journal={Symmetry Integrability and Geometry-methods and Applications}, year={2012}, volume={8}, pages={097} }
We construct a Lax pair for the $E^{(1)}_6 $ $q$-Painleve system from first principles by employing the general theory of semi-classical orthogonal polynomial systems characterised by divided-difference operators on discrete, quadratic lattices [arXiv:1204.2328]. Our study treats one special case of such lattices - the $q$-linear lattice - through a natural generalisation of the big $q$-Jacobi weight. As a by-product of our construction we derive the coupled first-order $q$-difference equations…
