Topological resolutions in K(2)-local homotopy theory at the prime 2

Algebraic Topology 2021-06-08 v2

Abstract

We provide a topological duality resolution for the spectrum E2hS21E_2^{h\mathbb{S}_2^1}, which itself can be used to build the K(2)K(2)-local sphere. The resolution is built from spectra of the form E2hFE_2^{hF} where E2E_2 is the Morava spectrum for the formal group of a supersingular curve at the prime 22 and FF is a finite subgroup of the automorphisms of that formal group. The results are in complete analogy with the resolutions of Goerss, Henn, Mahowald, and Rezk at the prime 33, but the methods are of necessity very different. As in the prime 33 case, the main difficulty is in identifying the top fiber; to do this, we make calculations using Henn's centralizer resolution.
