EHTW04 - Beyond the telescope conjecture

For a finite group G, Bredon equivariant motivic cohomology is an invariant for smooth G-schemes, over a base field, which mixes motivic cohomology and topological Bredon cohomology. For G=C_2, I’ll talk about a computation of the equivariant cohomology of C (joint with M. Voineagu and P. A. Ostvaer), a computation of the (completed) dual Steenrod algebra for this theory, and how these computations lead to an equivariant factorization of \tau.
