Straight projective-metric spaces with centres
It is proved that a straight projective-metric space has an open set of centres, if and only if it is either the hyperbolic or a Minkowskian geometry. It is also shown that if a straight projective-metric space has some finitely many well-placed centres, then it is either the hyperbolic or a Minkows...
