CMS Winter 2004 Meeting
We say that an infinite set S of closed points of an integral scheme X is critically dense if every infinite subset of S is Zariski dense in X. This property was introduced by Rogalski, who used
it to construct examples of noncommutative algebras with counter-intuitive properties.
