[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)

[edit] A proof for Dynkin's Lemma?

I suggest adding in a proof for Dynkin's Lemma.--A 20:00, 5 October 2007 (UTC)

I wonder, would [1] be an appropriate source?--A 20:04, 5 October 2007 (UTC)

If the site is self-published, as it appears to be, then it would not qualify unless the author is already a recognized (and published) expert on the topic. The author calls himself a derivatives trader. While he cold have a degree in statistics, we really don't know anything else about him or the website. See WP:RS and WP:V for the definitive rules. ·:· Will Beback ·:· 22:41, 5 October 2007 (UTC)
