by evaluation. Namely, w̃(g1, . . . , gm) is obtained by substituting gi in place of xi and g −1 i in place of x−1 i followed by computing the resulting value w(g1, . . . , gm). Word maps have been intensely studied over at least two past decades in various contexts (see, e.g., [?], [?], [?], [?] for surveys). In this paper, we consider the case where G = G(K) is the group of K-points of a simpl...
