comment How can I improve my chance of getting a tenure-track position
My impression (and CS may be different than math) is that there's a small number of "winner-take-all" candidates who interview everywhere and can take their pick of school (outside perhaps the top 5), but that in the 30-100 tier range mentioned in the post most jobs go to people who had a single-digit number of interviews and no more than 3 offers.

comment Symmetries of module categories over the category of representations of quantum $sl(2)$
If your category is Vec(G) for a finite group G, then any cohomology class $H^2(G,\mathbb{C}^\times)$ will give you a tensor autoequivalence of Vec(G) whose underlying functor is trivial. (You just use the cohomology class to define the natural tranformation $1_{gh} = \mathrm{id}(1_g \otimes 1_h) \rightarrow \mathrm{id}(1_g \otimes 1_h) = 1_{gh}$.)

You need to be a little careful, just counting the automorphisms isn't enough as you might have that some of them act trivially on the Grothendieck group.

comment What is $\infty^6$?
Doesn't it just mean the same (imprecise) thing as "There are six degrees of freedom"?

The proof has never appeared.
