Can someone clarify "the link of any simplex is a piecewise-linear sphere."? Dewa (talk) 21:20, 16 October 2008 (UTC)

I think this is still not right. E.g. for a traingulated 2-surface the link of an edge (1-simplex) is the boundary of an 1-simplex. More generally, it should be that for an n-manifold without boundary the link of a p-simplex is PL-homeomorphic to the boundary of an (n-p)-simplex. — Preceding unsigned comment added by Dimpase (talk • contribs) 17:54, 20 January 2020 (UTC)
