The congruence on semigroups

M. H. Shahzamanian

In this paper we define a congruence on semigroups. For the finite semigroups , is the smallest congruence relation such that is a nilpotent s…

Geometric characterizations of virtually free groups

Vítor Araújo, Pedro V. Silva

Four geometric conditions on a geodesic metric space, which are stronger variants of classical conditions characterizing hyperbolicity, are proved to be equivalent. In the particul…

Hölder conditions for endomorphisms of hyperbolic groups

Vítor Araújo, Pedro V. Silva

It is proved that an endomorphism of a hyperbolic group satisfies a Hölder condition with respect to a visual metric if and only if is virtually injective and is a…

Finiteness results for subgroups of finite extensions

Vitor Araujo, Pedro V. Silva, Mihalis Sykiotis

We discuss in the context of finite extensions two classical theorems of Takahasi and Howson on subgroups of free groups. We provide bounds for the rank of the intersection of subg…
