A structure theorem for RO(G)graded cohomology
Computations in RO(G)graded Bredon cohomology can be challenging and are not well understood, even using coefficients in a constant Mackey functor. In this talk I will present a structure theorem for RO(C_{2})graded cohomology with \mathbbZ/2 coefficients that substantially simplifies computations. The structure theorem says the cohomology of any finite C_{2}CW complex decomposes as a direct sum of two basic pieces: shifted copies of the cohomology of a point and shifted copies of the cohomologies of spheres with the antipodal action. I will sketch the proof, which depends on a Toda bracket calculation, and give some examples.
