Empty set (the Empty Set).An empty set is a set with no members or the number of members in the set to zero. The symbol can be written instead by {} or Ø.For example, theA = {x | x is an integer and x 2 < < 1} A = Ø ∴.B = {x | x is a positive integer and x + 1 = 0}, B = Ø ∴.Because we can tell how many members of the empty set is empty, the set is a set limit.
