From Wikipedia, the free encyclopedia
In mathematics, a Grothendieck universe is a set with the following properties:
  1. If xU and if yx, then yU.
  2. If x,yU, then {x,y} ∈ U.
  3. If xU, then P(x)U. (P(x) is the power set of x.)
  4. If is a family of elements of U, and if IU, then the union is an element of U.

A Grothendieck universe is meant to provide a set in which all of mathematics can be performed. (In fact, it provides a model for set theory.) As an example, we will prove an easy proposition...
