  • Abstract We study the concept of ‘rational subgroup’ introduced by S. Gersten and H. Short [Ann. of Math. 134 (1991) 125-158] in the context of geometrically finite hyperbolic groups. We show that if there are no parabolics, a subgroup is rational with respect to any automatic structure if and only if the subgroup is also geometrically finite. Some related questions are also discussed.
