A Whitehad algorithm for toral relatively hyperbolic groups

The Whitehead problem is solved in the class of toral relatively hyperbolic groups G (i.e. torsion-free relatively hyperbolic groups with abelian parabolic subgroups): there is an algorithm which, given two nite tuples (u1; ... ; un) and (v1; ... ; vn) of elements of G, decides whether there is an a...

Resumo:The Whitehead problem is solved in the class of toral relatively hyperbolic groups G (i.e. torsion-free relatively hyperbolic groups with abelian parabolic subgroups): there is an algorithm which, given two nite tuples (u1; ... ; un) and (v1; ... ; vn) of elements of G, decides whether there is an automorphism of G taking ui to vi for all i.
