Abstract:

We show that a simply connected homotopy associative and homotopy commutative mod $3$ $H$-space with finitely generated mod $3$ cohomology is homotopy equivalent to a finite product of $K({mathbb Z},2)$, $Sp(2)$, the three-connected cover $Sp(2)langle 3rangle$and the homotopy fiber $Sp(2)langle 3;3^irangle$of the map $[3^i]:Sp(2)to K({mathbb Z},3)$ for $ige 1$. Our result also shows that a connected $C_p$-space in the sense of Sugawara with finitely generated mod $p$ cohomology has the homotopy type of a finite product of $K({mathbb Z},1)$, $K({mathbb Z},2)$ and $K({mathbb Z}/p^i,1)$ for $ige 1$.

Keywords:$H$-space   $C_n$-space   Dror Farjoun localization functor
