    • Absolute Complement: If a universe U is defined, then the relative complement of A in U is called the absolute complement (or simply complement) of [math]A[/math], and is denoted by AC or sometimes A′, also the same set often is denoted by CU [math]A[/math] (or C A if U is fixed), that is:
        • AC = UA.
