A closed n-ball of radius r is the set of all points of distance less than or equal to r away from x. Visa mer One may talk about balls in any topological space X, not necessarily induced by a metric. An (open or closed) n-dimensional topological ball of X is any subset of X which is homeomorphic to an (open or closed) Euclidean n-ball.
