Mar 12, 2013 at 10:19 comment added Jeffrey Giansiracusa Ciprian Manolescu has just posted a paper in which he claims to prove that no such homology 3-sphere exists. arXiv:1303.2354 Pin(2)-equivariant Seiberg-Witten Floer homology and the Triangulation Conjecture
Apr 30, 2011 at 3:03 comment added Paul Yeah, acyclic PL manifold is clearer.
Apr 29, 2011 at 20:29 comment added algori I've found the paper. Question settled: a "PL acyclic manifold" is the same as an acyclic PL manifold.
Apr 29, 2011 at 20:17 comment added algori Paul -- I've accidentally stumbled upon this question. Thanks for your answer. Could you please clarify what "a PL acyclic" 4-manifold is.

Oct 29, 2010 at 1:31 comment added Igor Belegradek I take it back, Andy and Paul are right. By the way, the introduction to "The Hauptvermutung Book" explains this all in some detail: See maths.ed.ac.uk/~aar/books/haupt.pdf.
Oct 29, 2010 at 1:06 comment added Paul No. "combinatorial triangulation" is synomymous with "PL structure". See the MR. You are probably mistaking it with the Kirby Siebenmann invariant, which is the obstruction to finding a PL structure on a Topological manifold.
Oct 29, 2010 at 1:06 comment added Andy Putman @Igor : Galewski-Stern's theorem is definitely about noncombinatorial triangulations.
Oct 29, 2010 at 0:59 comment added Igor Belegradek Your answer is about combinatorial triangulations. The question is about arbitrary ones.
