In this paper we analyse convergence of projected fixed-point iteration on aRiemannian manifold of matrices with fixed rank. As a retraction method we use`projector splitting scheme'. We prove that the projector splitting schemeconverges at least with the same rate as standard fixed-point iteration withoutrank constraints. We also provide counter-example to the case when conditionsof the theorem do not hold. Finally we support our theoretical results withnumerical experiments.
