摘要

We consider \(G=Q_8,\textrm{SD}_{16},G_{24},\) G = Q 8 , SD 16 , G 24 , and \(G_{48}\) G 48 as finite subgroups of the Morava stabilizer group which acts on the height 2 Morava E-theory \({\textbf{E}}_2\) E 2 at the prime 2. We completely compute the G-homotopy fixed point spectral sequences of \({\textbf{E}}_2\) E 2 . Our computation uses recently developed equivariant techniques since Hill, Hopkins, and Ravenel. We also compute the \((*-\sigma _i)\) ( - σ i ) -graded \(Q_8\) Q 8 - and \(\textrm{SD}_{16}\) SD 16 -homotopy fixed point spectral sequences, where \(\sigma _i\) σ i is a non-trivial one-dimensional representation of \(Q_8\) Q 8 .
