What role does the quantum torus play in Noncommutative geometry
I agree that the question is too broad in its current form, but you may be interested in arxiv.org/abs/0802.4033

Dual of Banachvalued $L^p$
@AndréHenriques just to add to Tomek's comment: X has RNP if and only if every bounded subset of X has the following geometric property ("dentability"): for each $r>0$ there is a point $x\in X$ that does not lie in the convex hull of $X\setminus$ (rneighbourhood of $x$)

Is each multiplicative linear functional on $L^1(SL(2,R):SO(2,R))$ is triviall?
Oh, my mistake: I was thinking of SO(3)biinvariant functions. Your question is asking about onesided SO(3)invariant functions, right?

Exactness of total complex
And what you're after does seem like a "collapse at E_2" argument to me  there should be examples in Weibel's book where exactly this situation occurs, i.e. homology in each row vanishes except at one end

comment 
Exactness of total complex
The modified question is better but I think it is still too vague. Instead of asking "is there some kind of partial result", why not say "if I assume these conditions X, can I still conclude Y"?

Survey of Erdős' “Tricks”
@MariusKempe I like Rota's writing style but he was famously fond of being polemical, and Rota saying "X was like this" is not exactly gospel. The rest of the essays and anecdotes in "Indiscrete Thoughts" would bear this out

Survey of Erdős' “Tricks”
On the old version of MathOverflow, at one point, there was a maxim "MathOverflow is not for requests for people to write encyclopaedia entries for you." Times may have changed, but I really feel that this kind of question is just a fishing expedition

An integral with respect to the Haar measure on a unitary group
Do you need an exact answer or would large $n$ asymptotics suffice? In the second situation, in the case where $A$ and $D$ are diagonal with free entries, one might be able to use an approximation of the spectral distribution of $AHDH^*$ ($H$ chosen uniformly at random) by the free convolution of $\mu_A$ with $\mu_D$, see e.g. the first few pages of arxiv.org/abs/math/9809193

comment 
Dual of Banachvalued $L^p$
Just to clarify: presumably there is a missing quantifier, and the full result is: the dual has the desired form for all $\sigma$finite $(\Omega,\mu)$ if and only if $X^*$ has RNP?

Dual of Banachvalued $L^p$
Typo: you mean $L^{p'}({\mathbb R}, X^*)$, right?
