Chromatic splitting for the $K (2)$ -local sphere at $p = 2$

Agnes Beaudry, Paul G. Goerss, Hans-Werner Henn

We calculate the homotopy type of $L_{1} L_{K (2)} S^{0}$ and $L_{K (1)} L_{K (2)} S^{0}$ at the prime 2, where $L_{K (n)}$ is localization with respect to Morava $K$ -theory and $L_{1}$ localizati…

A Mini-Course on Morava Stabilizer Groups and Their Cohomology

Hans-Werner Henn

The Morava stabilizer groups play a dominating role in chromatic stable ho-motopy theory. In fact, for suitable spectra X, for example all finite spectra, thechromatic homotopy typ…

On the Mod-2 Cohomology of SL 3 (z[ 1 2 , i])

Hans-Werner Henn

Let $Γ$ = SL 3 (Z[ 1 2 , i]), let X be any mod-2 acyclic $Γ$ -CW complex on which $Γ$ acts with finite stabilizers and let Xs be the 2-singular locus of X. We calculate the mod-2 co…
