Extremal pseudocompact Abelian groups: A unified treatment

William Wistar Comfort, Jan van Mill (2013)

Commentationes Mathematicae Universitatis Carolinae

The authors have shown [Proc. Amer. Math. Soc. 135 (2007), 4039--4044] that every nonmetrizable, pseudocompact abelian group has both a proper dense pseudocompact subgroup and a strictly finer pseudocompact group topology. Here they give a comprehensive, direct and self-contained proof of this result.
