Let (M, d) be a metric space, namely a set M with a metric (distance function) d. The open (metric) ball of radius r > 0 centered at a point p in M, usually denoted by Br(p) or B(p; r), is defined by The closed (metric) ball, which may be denoted by Br[p] or B[p; r], is defined by Note in particular that a ball (open or closed) always includes p itself, since the definition requires r > 0.
