Abstract |
|
We compute the cohomology of the subalgebra AC2(1) of the C2-equivariant Steenrod algebra AC2. This serves as the input to the C2-equivariant Adams spectral sequence converging to the completed RO(C2)-graded homotopy groups of an equivariant spectrum koC2. Our approach is to use simpler C-motivic and R-motivic calculations as stepping stones. |
