Abstract:In this paper we analyze the localization of $W(n)$, the fiber of the double suspension map $S^{2n-1}to Omega^{2}S^{2n+1}$, with respect to $E(2)$. If four cells at the bottom of $D_pM^{2np-1}$, the $p$th extended power spectrum of the Moore spectrum, are collapsed to a point, then one obtains a spectrum $C$. Let $QM^{2np-1}to QC$ be the James-Hopf map followed by the collapse map. Then we show that the secondary suspension map $BW(n)to QM^{2np-1}$ has a lifting to the fiber of $QM^{2np-1}to QC$ and this lifting is shown to be a $v_2$-periodic equivalence, hence an $E(2)$-equivalence.

Keywords:{$L_2$}-localization   double suspension   {$v_2$}-periodicity
