Abstract
The Brouwer fixed point theorem states that the disk has the fixed point property. More generally, by the Lefschetz fixed point theorem any compact ANR with trivial rational homology has the fixed point property. In this note we prove that for any connected compact CW-complex there exists a space weak homotopy equivalent to which has the fixed point property. The result is known to be false if we require to be a polyhedron. The space we construct is a non-Hausdorff space with finitely many points.
