Householder reflextion for optimization on Grassman manifolds

We present Householder reflextors for optimization problems inspired by electronic structure calculations. Using the Householder operation to update the solution ensures that the solution stays in the feasible region. We will also describe how to construct a gradient based iterative solver on the Grassman manifold.
