Maximizing entropy under constraints
Thanks for your detailed answer; I must say that a quick look at the references you mention did not enable me to find what I looked for: I found interpretation in terms of multifractal spectra of such maximization problems, but not the description of how a maximizing (Gibbs) measure can be found. But you warned about the fact that these are implicit, so I guess I just need to take a more careful look.

Maximizing entropy under constraints
@AnthonyQuas: the pointer to Christian Wolf and Tamara Kucherenko is so good that it could be made an answer; it seems after a quick look that their work does contain this application of our work. Thanks!

Corrected my guess to a less obviously flase one.

@ChristianRemling: you are of course right. I will edit my guess.

@ChristianRemling: sorry, the question had a mistake: the first convergence is about the derivative $\varphi_n'$.

cobordism and smothmanifold
Your question does not has a question. If you are asking whether the last sentence is implied by the previous ones, then it looks like a standard exercise about manifolds and probably not a good fit for MO.

Copypasted the improved version from math.SE where it will probably do not get the attention by experts it deserves.

A variation on the local Günther inequality
@JonMarkPerry: yes, I am sure that I don't see your point, and that the very classical properties of nonpositively curved manifolds stated on wikipedia (which does not even mentions the classical Günther inequality) do not answer my question. Now, if you claim to have a solution, you are very welcome to propose it and I would be more than happy to give the bounty if it stands right. But throwing obvious facts without apparent relation to the question is useless.

A variation on the local Günther inequality
@JonMarkPerry: I sure know that cosh is an antiderivative of sinh, and I don't quite see your points. This question lies quite beyond the content of wikipedia.

A variation on the local Günther inequality
@BS.: this paper looks interesting; it might be possible to use it to reduce the matricial problem to a scalar problem, which is basically the case we know how to handle. Otal's paper only works with one derivative though, so it will need some work to see how it goes.

Modern Mathematical Achievements Accessible to Undergraduates
It seems pretty ambitious to me: I advised a lecture group for pretty bright undergrads with the goal of understanding this proof, and a dozen twohours sessions where not sufficient to go to the end of ot; note that the students had no background in dynamical systems.
