In the mathematical field of topology a uniform isomorphism or uniform homeomorphism is a special isomorphism between uniform spaces which respects uniform properties.

Definition

A function f between two uniform spaces X and Y is called a uniform isomorphism if it satisfies the following properties

  • f is a bijection
  • f is uniformly continuous
  • the inverse function f -1 is uniformly continuous
  • If a uniform isomorphism exists between two uniform spaces they are called uniformly isomorphic or uniformly equivalent.

    Examples

    The uniform structures induced by equivalent norms on a vector space are uniformly isomorphic.
