The Mathematical Intelligencer, 1992
By taking appropriate concrete functions on the complex or real numbers, in this nicely written survey the author shows that free groups and free products of groups occur naturally and explicitly. We just mention two of the results surveyed: \textit{S. A. Adeleke, A. M. W. Glass} and \textit{L. Morley} [J. Lond. Math. Soc., II. Ser. 43, No. 2, 255-268 (

Free Groups and Free Products of Groups
1991In the preceding chapters we have introduced the fundamental group of a space and actually determined its structure in some of the simplest cases. In more complicated cases we need a larger vocabulary and a greater knowledge of group theory to describe its structure and actually to make use of its properties.

PSEUDOCHARACTERS ON FREE GROUPS
Russian Academy of Sciences. Izvestiya Mathematics, 1995Let \(G\) be a group. A real function \(\varphi\) from \(G\) is called a pseudocharacter if there exists an \(\varepsilon > 0\) such that \(|\varphi (xy) - \varphi (x) - \varphi (y)|< \varepsilon\) for any \(x, y \in G\) and \(n \varphi (x) = \varphi (x^n)\) for any \(x \in G\) and any integer \(n\).

Free Subgroups of Free Topological Groups
1974It is well known that every subgroup of a free group is a free group. However, it is not true in general that a subgroup of a free topological group is a free topological group.
