Which math paper maximizes the ratio (importance)/(length)?
I think the really impressive thing is the paper has no mathematical symbols in it (it must have been tempting to add at least an $\epsilon$).

Is there a nonexplicit characterization of the Specht modules?
@DavidSpeyer You mentioning that was definitely worthwhile (I had no idea that that was the case).

Status of Borho and Brylinski's irreducibility conjectures?
@GeordieWilliamson By the time I saw you talk about this, I'd forgotten this question; I think the inverses of the elements you give should be a counterexample to the conjecture above. Do you feel like adding that as an answer?

BeilinsonBernstein localization: $\mathfrak{g}$ action on $G$equivariant sheaf
@NilayKumar The function $g$ is the derivative of f with respect to $a$. This is proven exactly like the multiplication rule in first year calculus.

Deformations of associative algebras and Hochschild cohomology
You're really trying to reinvent the wheel here. This is all in Hochschild's papers "The deformation theory of rings and algebras IIV" from the 60's.

Mixed Hodge structure and cup product
Also, seriously? 3 close votes? I understand it's not the best written question and the answer is reasonably "wellknown," but mixed Hodge structures are too basic for this site now?
