On the profinite rigidity of surface groups and surface words
Comptes Rendus. Mathématique, Volume 359 (2021) no. 2, pp. 119-122.

Surface groups are determined among limit groups by their profinite completions. As a corollary, the set of surface words in a free group is closed in the profinite topology.
