nLab > Latest Changes: unordered pair

Bottom of Page

1 to 3 of 3

  1.  

  1. added definition of the type of unordered pairs in dependent type theory

    diff, v6, current

  2. The type theoretic definition is missing a set-truncation constructor. The current definition of the type of unordered pairs defined for the unit type gives the circle type.

  3. added axiom K to the constructors of the unordered pair type
