Goresky–MacPherson Calculus for the Affine Flag Varieties
Published online by Cambridge University Press: 20 November 2018
Abstract
We use the fixed point arrangement technique developed by Goresky and MacPherson to calculate the part of the equivariant cohomology of the affine flag variety $\mathcal{F}{{\ell }_{G}}$ generated by degree 2. We use this result to show that the vertices of the moment map image of
$\mathcal{F}{{\ell }_{G}}$ lie on a paraboloid.
