By definition, a projection is idempotent (i.e. ). Every projection is an open map, meaning that it maps each open set in the domain to an open set in the subspace topology of the image. That is, for any vector and any ball (with positive radius) centered on , there exists a ball (with positive radius) centered on that is wholly contained in the image .
