In topology and related areas of mathematics a uniformly connected space or Cantor connected space is a uniform space ''U'' such that every
uniformly continuous function In mathematics, a real function f of real numbers is said to be uniformly continuous if there is a positive real number \delta such that function values over any function domain interval of the size \delta are as close to each other as we want. In ...
from ''U'' to a discrete uniform space is constant. A uniform space ''U'' is called uniformly disconnected if it is not uniformly connected.
