• Resumen

  • In a previous article we showed how one can see the classical result on existence and uniqueness of a fundamental set of factorial series solutions of a regular di.erence system as the limit, when q tends to 1, of analogous results for a q-di.erence system obtained by some kind of deformation. We extend here this property to singular-regular (or Fuchsian) systems.
