Abstract (EN):
It is proved that an endomorphism ¿ of a hyperbolic group G satisfies a Hölder condition with respect to a visual metric if and only if ¿ is virtually injective and G¿ is a quasiconvex subgroup of G. If G is virtually free or torsion-free co-hopfian, then ¿ is uniformly continuous if and only if it satisfies a Hölder condition if and only if it is virtually injective. © 2016, Copyright © Taylor & Francis Group, LLC.
