[edit] λ system

The equivalent λ system is defined as follows: Definition. A family L of subsets of C is called a λ-system if

(1) Ω belongs to L,
(2) L is closed under complementation,
(3) L is closed under countable unions of pw disjoint sets.

Given any class C of sets, L(C) denotes the λ-system generated by C. Jackzhp 23:50, 28 October 2006 (UTC)
