An elementary construction of Anick's fibration

##### Abstract

Cohen, Moore, and Neisendorfer’s work on the odd primary homotopy theory of spheres and Moore spaces, as well as the first author’s work on the secondary suspension, predicted the existence of a $p$–local fibration ${S}^{2n-1}\to {T}_{2n-1}\to \Omega {S}^{2n+1}$ whose connecting map is degree ${p}^{r}$. In a long and complex monograph, Anick constructed such a fibration for $p\ge 5$ and $r\ge 1$. Using new methods we give a much more conceptual construction which is also valid for $p=3$ and $r\ge 1$. We go on to establish an $H$ space structure on ${T}_{2n-1}$ and use this to construct a secondary $EHP$ sequence for the Moore space spectrum.
