Complement (set theory) 补集

(重定向自Relative complement)
The absolute complement of A in U:
Ac = U \ A
相对补集A - B
绝对补集

In set theory, a complement of a set A refers to things not in (that is, things outside of) A. The relative complement of A with respect to a set B is the set of elements in B but not in A. When all sets under consideration are considered to be subsets of a given set U, the absolute complement of A is the set of all elements in U but not in A.
