    Abstract

    Let F(X) (A(X)) be the free (Abelian) topological group over X. We prove: If P is one of the spaces R, Q, R, Q, βω, βω ω and 2/gk for an infinite κ and if F(X) or A(X) contains a copy of P, then X contains a copy of P. If P is the one-point compactification of an infinite discrete space or ω1 + 1, this is not true. If P = ω1, this holds for F(X) but is independent of ZFCfor A(X).
