Profinite completions of the fundamental group of the Klein bottle. (English) Zbl 0609.57001

Author’s summary: ”A compactification of the fundamental group of the Klein bottle is obtained by means of the determination of its profinite completion. The Sylow decomposition of this group is expressed in terms of p-profinite completions for each prime number p. Several finiteness, centrality and radical properties are established.”
