comment Cohomology spectral sequence over $k[t]$
David: This might be worth checking out: arxiv.org/abs/1112.1245 We never ended up nailing down low-level details for making this work for distributed computing in that preprint, which is why I'm trying to figure out how to do the same things in a cohomological sequence now.

comment Bounded convolutions with binomial coefficients
No, this is unrelated to the tie-knot thing; it's for a complexity analysis of an algorithm.

comment Intuitionistic algebraic topology?
The context I'm working on is, to be more exact, what happens if I do topology internal to a particular topos of sheaves.
