FREE ABELIAN TOPOLOGICAL GROUPS ON SPHERES

The Quarterly Journal of Mathematics, 1984
If X is a completely regular topological space, then the abelian topological group F(X) is a (Markov) free abelian topological group on X if X is a subspace of F(X), X generates F(X) algebraically and for every continuous mapping \(\phi\) of X into any abelian topological group G there exists a continuous homomorphism \(\Phi\) of F(X) into G that ...

Free subgroups of free abelian topological groups

Mathematical Proceedings of the Cambridge Philosophical Society, 1986
In this paper we prove a theorem which gives general conditions under which the free abelian topological group F(Y) on a space Y can be embedded in the free abeian topological group F(X) on a space X.

Open subgroups of free abelian topological groups

Mathematical Proceedings of the Cambridge Philosophical Society, 1993
We prove that any open subgroup of the free abelian topological group on a completely regular space is a free abelian topological group. Moreover, the free topological bases of both groups have the same covering dimension. The prehistory of this result is as follows.

EMBEDDING OF THE FREE ABELIAN TOPOLOGICAL GROUP INTO

Mathematika, 2019
We consider the following question: for which metrizable separable spaces does the free abelian topological group isomorphically embed into . While for many natural spaces such an embedding exists, our main result shows that if is a Cook continuum or is a rigid Bernstein set, then does not embed into as a topological subgroup.
