at some point a needed to work a lower bound for $\text{E}_q[\log \sum_k X_k]$. After seeing some people using this lower bound without a good explanation, I decided to write this blog post. Also, thi... | {} |

it would be if x > =0 then |x| = x yes?
if $\left| x \right|=x,then x <, 0$

### Fubini Properties of Ideals
#### Abstract
Let $I$ and $J$ be \s-ideals on Polish spaces $X$ and $Y$, respectively. We say that the pair $\langle I,J\rangle$ has the Fubini Property (FP) if for every Borel subset $B$ of $X\times Y$, if all its sections $B_x= \{y\: \langle x,y\rangle\in B... | {} |
