Algebraic Topology 2024-01-24 v3

Abstract

We consider G=Q8,SD16,G24,G=Q_8,SD_{16},G_{24}, and G48G_{48} as finite subgroups of the Morava stabilizer group which acts on the height 22 Morava EE-theory E2\mathbf{E}_2 at the prime 22. We completely compute the GG-homotopy fixed point spectral sequences of E2\mathbf{E}_2. Our computation uses recently developed equivariant techniques since Hill, Hopkins, and Ravenel. We also compute the (σi)(*-\sigma_i)-graded Q8Q_8- and SD16SD_{16}-homotopy fixed point spectral sequences, where σi\sigma_i is a non-trivial one-dimensional representation of Q8Q_8.
