Is every number the sum of two cubes modulo p where p is a prime not equal to 7?
There should be a simpler proof using the Cauchy Davenport inequality. (We might need Vosper's result which also characterizes when equality can happen)

@ChristianStump, If you want you can upgrade your comment to an answer (I would accept it :)). What I had in mind was to compute cohomology in different ways (perhaps localize with respect to different group actions or something along those lines), but since this wouldn't distinguish the symmetric group among other Weyl/Coxeter groups, I am less hopeful because of the reasons you mention.

How do I check that this is a Frobenius algebra?
@AndréHenriques The main steps are roughly: 1) Reduce the global duality theorem (the statement in your question) to the local case around a single zero. 2) Prove it for the case $f_i=z_i^{k_i}$. 3) Deduce the general form by using the transformation formula (which says that if you take the residue with respect to $Af$ then the residue changes by factor of $\det (A)$.)

A curious GaussSum type identity
What is the numerator when $j=1$? Or is the "j2" a typo?

Proving that the Jones polynomial is qholonomic
Thanks, this was very helpful! I would be curious to see a proof of holonomicity using the cabling formula involving the polynomial representation of DAHA. I will check the references you gave.

Largest possible volume of the convex hull of a curve of unit length
This is the same as the curve mentioned in my answer, right? I believe the reference goes further back than 2010 :)
