Closed Disk


ClosedDisk

An n-dimensional closed disk of radius r is the collection of points of distance <=r from a fixed point in n-dimensional Euclidean space. Krantz (1999, p. 3) uses the symbol D^_(x,r) to denote the closed disk, and D^_=D^_(0,1) to denote the unit closed disk centered at the origin
