Topological resolutions in ‐local homotopy theory at the prime 2

I Bobkova, PG Goerss - Journal of Topology, 2018 - Wiley Online Library
We provide a topological duality resolution for the spectrum E 2 h S 2 1, which itself can be
used to build the K (2)‐local sphere. The resolution is built from spectra of the form E 2 h F …
