Abstract

In this paper, we prove that the homotopy localization of an AC_n-space is an AC_n-space so that the universal map is an AC_n-map. This result is used to study the higher homotopy commutativity of H-spaces with finitely generated cohomology over the Steenrod algebra A_p^*. Our result shows that for any prime p, if X is a connected AC_p-space whose mod p cohomology H^*(X; Z ∕ p) is finitely generated as an algebra over A_p^*, then X has the mod p homotopy type of a Postnikov H-space.
