### Where can I find that Weil suggested a cohomology theory for characteristic $p>0$?

As already mentioned in the comments it is very likely that Weil's heuristics appear in "Numbers of solutions of equations in finite fields", Bull. Amer. Math. Soc. 55(5): 497--508 (May 1949)...

### Is the number of "breakthroughs" in mathematics decreasing, as it is claimed to be in other sciences?

I think that the picture is complex, and I'm sure that the two (currently) top comments by David Roberts and Brendan McKay, although providing arguments in apparently opposite directions, are both ...

### Algebraic graph invariant $\mu(G)$ which links Four-Color-Theorem with Schrödinger operators: further topological characterizations of graphs?

The following embeddability characterization for $\mu(G)\le 5$ is merely a conjecture, but I think it fits the question:
Conjecture (van der Holst, [1]): $\mu(G)\le 5$ if and only if $G$ is 4-flat.

### Reference request for recurrence relation of division polynomials

These recurrences are stated explicitly in Weber's Lehrbuch der Algebra (published in 1908). See volume 3, section 58, page 200. Weber doesn't give a citation to them, so it's hard to know if they ...
