Some Special Profinite Groups

Chapter
Part of the Ergebnisse der Mathematik und ihrer Grenzgebiete. 3. Folge / A Series of Modern Surveys in Mathematics book series (MATHE3, volume 40)

Abstract

Let G be a profinite group and xG. Since \(\widehat {\mathbf{Z}}\) is a free profinite group on {1}, there is a unique epimorphism
$$\varphi :\widehat{\mathbf{Z}}\longrightarrow \overline {\langle x\rangle }$$
such that φ(1)=x. Given \(\lambda \in \widehat {\mathbf{Z}}\), define x λ =φ(λ).
