On conjugacy classes of the pro-\(\ell\) braid group of degree 2. (English) Zbl 0618.20022

The author extends a result of Y. Ihara [Ann. Math., II. Ser. 123, 43-106 (1986; Zbl 0595.12003), Corollary to Proposition 8] by showing that in some special subset of the pro-\(\ell\)-braid-group of degree 2 there are not only two (as Ihara proved) but infinitely many conjugacy classes.
