Spanier--Whitehead duality in the K(2)-local category at p=2
Abstract: The fixed point spectra of Morava E-theory $E_n$ under the action of finite subgroups of the Morava stabilizer group $\mathbb{G}_n$ and their K(n)-local Spanier--Whitehead duals can be used to approximate the K(n)-local sphere in certain cases. For any finite subgroup F of the height 2 Morava stabilizer group at p=2 we prove that the K(2)-local Spanier--Whitehead dual of the spectrum $E_2{hF}$ is $\Sigma{44}E_2{hF}$. These results are analogous to the known results at height 2 and p=3. The main computational tool we use is the topological duality resolution spectral sequence for the spectrum $E_2{h\mathbb{S}_21}$ at p=2.
