Proof that $E(X|sigma (G_1,G_2))=E(X|G_1)$, when $G_2,sigma(sigma(X),G_1)$ independent.
I want to prove:
$$E(X|sigma (G_1,G_2))=E(X|G_1)$$
when $G_2,sigma(sigma(X),G_1)$ are independent. It's quite elusive expression to unpack, what would you say is the meaning? Previously I have proven that:
$L={Ain F| E(I_AX)=E(I_AE(X|G_1)}$ is a $lambda$-system and contains the set: ${ Acap B| Ain G_1,Bin G_2}$. Note that $F$ is the simga algebra of the space which $G_1,G_2$ are subsets of.
How to continue from here?
