A Freeness Theorem for RO(Z/2)-graded Cohomology
arXiv:0908.3825
Abstract
In this paper it is shown that the RO(Z/2)-graded cohomology of a certain class of Rep(Z/2)-complexes, which includes projective spaces and Grassmann manifolds, is always free as a module over the cohomology of a point when the coefficient Mackey functor is \underline{Z/2}.
