The duality resolution at

Agnès Beaudry, Irina Bobkova, Hans-Werner Henn

Working at the prime and chromatic height , we construct a finite resolution of the homotopy fixed points of Morava -theory with respect to the subgroup …

The Exotic -Local Picard Group at the Prime

Agnes Beaudry, Irina Bobkova, Paul G. Goerss +3

We calculate the group of exotic elements in the -local Picard group at the prime and find it is a group of order isomorphic to $(\mathbb{Z}/8)^2 \times (\mat…

Cohomology of the Morava stabilizer group through the duality resolution at

Agnes Beaudry, Irina Bobkova, Paul G. Goerss +3

We compute the continuous cohomology of the Morava stabilizer group with coefficients in Morava -theory, , at , for , using the Algebr…

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