A $$3\times 3$$ linear q-difference system with $$E_8^{(1)}$$-symmetry

Abstract We present a linear q -difference equation of rank 3, which admits the affine Weyl group symmetry of type $$E_8^{(1)}$$ E 8 ( 1 ) . This equation has essentially 8 parameters and 2 accessory parameters. We characterize this equation by the spectral type of q -difference...
