We show that, for any ≠ 2, most orientation preserving homeomorphisms of the sphere have a Cantor set of fixed points. In other words, the set of such homeomorphisms that do have a Cantor set of fixed points is of the first Baire category within the set of all homeomorphisms. Similarly, most orientation reversing homeomorphisms of the sphere have a Cantor set of fixed points for any ≠ 0. Read More
