Idea

The Sullivan conjecture (due to Dennis Sullivan, now a theorem due to Miller 84) states that – under certain conditions and after suitable p-adic completion – the canonical map for a G-space from its ordinary fixed points to its homotopy fixed points is a weak homotopy equivalence.

A proof was given in Carlsson 91, using the Segal-Carlsson theorem.
