Profinite extensions of centralizers and the profinite completion of limit groups
Profinite extensions of centralizers and the profinite completion of limit groups
We introduce and investigate a class of profinite groups defined via extensions of centralizers analogous to the extensively studied class of finitely generated fully residually free groups, that is, limit groups (in the sense of Z. Sela). From the fact that the profinite completion of limit groups belong to this …
