Answering a question of Comfort and Gould, we completely describe the algebraic structure of abelian topological groups having the small subgroup generating property. We construct a countable free closed non-relexive subgroup in the product of continuum many integers. We introduce a notion of selectively sequentially pseudocompact space and study basic properties of this new subclass of pseudocompact spaces. Answering a question of Tkachenko, we prove that a weakly pseudocompact precompact group is pseudocompact.

(In particular, potential denseness of a set in G can be witnessed by some precompact group topology of G.) New metrizability criteria for compcat groups are obtained. We also provide various characterizations of Lie groups by means of controlling their zero-dimensional closed subgroups. Multiplier convergence theory of topological groups is developed.
