A Hausdorff topological group G = (G, T ) has the small subgroup generating property (briefly: has the SSGP property, or is an SSGP group) if for each neighborhood U of 1G there is a family H of subgroups of G such that H ⊆ U and H is dense in G. The class of SSGP groups is defined and investigated with respect to the properties usually studied by topologists (products, quotients, passage to dense subgroups, and the like), and with respect to the familiar class of minimally almost periodic groups (the m.a.p. groups). Additional classes SSGP(n) for n < ω (with SSGP(1) = SSGP) are defined and investigated, and the class-theoretic inclusionsare established and shown proper. In passing the authors also establish the presence of SSGP(1) or SSGP(2) in many of the early examples in the literature of abelian m.a.p. groups.2010 MSC: Primary 54H11; Secondary 22A05.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
