Faculty of Engineering and Information Sciences - Papers: Part A
We show that the subspace An(X) of the free Abelian topological group A(X) on a Tychonoff space X is locally compact for each n ω if and only if A2(X) is locally compact if an only if F2(X) is locally compact if and only if X is the topological sum of a compact space and a discrete space. It is also proved that the subspace Fn(X) of the free topological group F(X) is locally compact for each n …
