AbstractThe set of projector frames (i.e. finite sequences of commuting projectors which sum to the identity) can be given a differentiable manifold structure with an affine connection. We compare the resulting geodesic arcs with other naturally arising paths and find them cubically close. We also discuss Riemannian geodesics in an appropriate Hilbert-space context
