comment Convergence in mean square from expected value/variance
Hmm, this is very simple. I think my mind was rebelling at the implication that this implies almost-sure convergence for a subsequence of ${X_n}$. The latter fact seems too good to be true...

comment Dividing by an almost-surely positive random variable
So Y/Z is not a random variable (a function), but it is integrable with respect to this measure? Is there a name for this kind of "function"?

Ahh!! I'm foolish. My integral for z < 0 should be $\displaystyle\int_{-z}^\infty$. Thanks Nate.

comment Density of a function of random variables
Nate, I had a typo, the $z>0$ and $z<0$ regions were flipped. I agree that my $z<0$ part is giving the problem, but I don't see how to fix it.

comment Ext & Complexes
In Vista 3.4.6, Weibel says "... the set of equivalence classes ... (if this is indeed a set)", and then claims that $Ext^1(A,B)$ is an abelian group. How can $Ext^1$ not be a set, and still be an abelian group?
