ms: metric spaces

[ bsd2, library, math ] [ Propose Tags ]

A MetricSpace is a set together with a notion of distance between elements. Distance is computed by a function dist which has the following four laws:

  1. non-negative: forall x y. dist x y >= 0

  2. identity of indiscernibles: forall x y. dist x y == 0 <=> x == y

  3. symmetry: forall x y. dist x y == dist y x

  4. triangle inequality: forall x y z. dist x z <= dist x y + dist y z

See the Wikipedia article on metric spaces for more details.
