Abstract

Let C be a nonempty class of finite groups [this will always mean that C contains all the isomorphic images of the groups in C]. Define a pro — C group G as an inverse limit
$$G = \mathop {\underleftarrow {\lim }}\limits_{i \in I} {G_i}$$
of a surjective inverse system {G i, φij I} of groups G i in C, where each group G i is assumed to have the discrete topology. We think of such a pro — C group G as a topological group, whose topology is inherited from the product topology on П i∈I G i.
