comment Circle actions on graph C*-algebras
@ChrisRamsey: oh, I see. I'm guessing the answer to the second part is "no" but I'd like to see the definition of "quotient".

@ChrisRamsey: is that in response to my question? This is not what I asked.

comment Circle actions on graph C*-algebras
For those who aren't very familiar with graph C*-algebras, could you please define "quotient of a graph algebra by an action"?

@truebaran: this seems like a very complete answer to your question, why don't you accept it?

comment Measure of intersections in probability spaces
(The theorem you could cite is that this space is measurably equivalent to the interval $[0,\delta]$, but for the purpose of constructing a counterexample you could just work with the product space union an interval of length $\epsilon$. So the citation is unnecessary.)

comment Measure of intersections in probability spaces
For the existence of the $B_i$, you could do this: work in the product of a sequence of copies of $[0,1]$ and let $B_i'$ be the product of $[0,(1-2^{-i})\frac{\epsilon}{\delta}]$ on the $i$th factor and $[0,1]$ on ever other factor, where $\delta = 1-\epsilon$. Then scale the whole product by $\delta$.

This is the right way to do it.
