Free Topological Groups and the Projective Dimension of a Locally Compact Abelian Group
It is shown that a free topological group on a kaspace is a ArM-space.Using this it is proved that if A" is a Ar^-group then it is a quotient of a free topological group by a free topological group.A corollary to this is that the projective dimension of any Ä^-group, …
