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 .
