abstract

  • Abstract We give a complete description of the topological spaces X such that the free abelian topological group A (X) embeds into the free abelian topological group A (I) on the closed unit interval. In particular, the free abelian topological group A (X) on any finite- dimensional compact metrizable space X embeds into A (I). To obtain our description, we study similar embeddings of the free locally convex spaces and continuous surjections between the spaces of continuous functions with the pointwise topology. Proofs are based on the classical Kolmogorov's Superposition Theorem.
