ulmcau

Description: A sequence of functions converges uniformly iff it is uniformly Cauchy, which is to say that for every 0 < x there is a j such that for all j <_ k the functions F ( k ) and F ( j ) are uniformly within x of each other on S . This is the four-quantifier version, see ulmcau2 for the more conventional five-quantifier version. (Contributed by Mario Carneiro, 1-Mar-2015)
