Abstract

The fixed point spectra of Morava E-theory EnE_n under the action of finite subgroups of the Morava stabilizer group Gn\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 E2hFE_2^{hF} is Σ44E2hF\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 E2hS21E_2^{h\mathbb{S}_2^1} at p=2.
