Ball (Mathematics)

Definition : Let P,Q be points on a space, the ball \mathbb{B}_n (P) = \{ Q| \mid P - Q \mid < n\}

The unit ball \mathbb{B}_n (P) are all points in the space whose distance from P is less then n. This is also called an open unit ball. A closed unit ball is where all points whose distance from P is equal to n is also included. A unit ball is a ball where n = 1
