The Exotic $K (2)$ -Local Picard Group at the Prime $2$

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

We calculate the group $I^º_{2}$ of exotic elements in the $K (2)$ -local Picard group at the prime $2$ and find it is a group of order $2^{9}$ isomorphic to $(\mathbb{Z}/8)^2 \times (\ma…

The duality resolution at $n = p = 2$

AgnÃ¨s Beaudry, Irina Bobkova, Hans-Werner Henn

Working at the prime $2$ and chromatic height $2$ , we construct a finite resolution of the homotopy fixed points of Morava $E$ -theory with respect to the subgroup $G_{2}^{1}$ …
