Normalisers in Limit Groups
Bridson, Martin R · Howie, James
Original · EN
Let be a limit group, S⊂ a subgroup, and N the normaliser of S. If H₁(S,Q) has finite -dimension, then S is finitely generated and either N/S is finite or N is abelian. This result has applications to the study of subdirect products of limit groups.
