Applications of really large numbers
Are you primarily interested in applications of individual large numbers (such as the Skewes number, which by now is just an artifact, or Graham's number which has a curious provenance), or in fastgrowing sequences? I'd think it is the latter that has greater theoretical significance.

A question about the Sylvester determinant
@user49039 Maybe you should say what Rosalind is; otherwise the comment is not very constructive.

Why is a braided left autonomous category also right autonomous?
Thanks, Peter. Our answers hopefully make it clear (I spelled everything out on my nLab web page).

Why is a braided left autonomous category also right autonomous?
You know, it's not just one axiom that needs to be applied. It's a longish derivation; see the answers by Peter and me (my answer directs you to a personal web page of mine).

Regarding to $ \lim_{N\rightarrow \infty}\sum_{n=1}^{N+1}\sum_{k=n1}^{N}C_{kn}$, prove or disprove!
Nevertheless, this is the wrong site for this type of question, which is for mathematicians engaged in research. Such questions should be asked at Mathematics StackExchange. Migrating it now...

Is it possible to give a fair assessment of the influence of Bourbaki's “Eléments de mathématique”?
There is a serious attempt to assess the influence of what Bourbaki proposed as the central concept of the entire Elements corpus, namely that of Structure, by Leo Corry: tau.ac.il/~corry/publications/articles/bourbakistructures.html. It can be argued, for various reasons, that this concept did not "take". On the other hand, we have the masterly Lie Groups and Lie Algebras which really set a standard for generations. So it seems to me an assessment of the influence of the Elements might best proceed on a bookbybook basis.

Level sets of a Weierstrass nowheredifferentiable function
Again, thanks very much for the wealth of detailed information. Unfortunately, this answer has been flagged for reasons similar to those given in reaction to the other recent post (in the thread you cited at the beginning), and so my comment there applies here as well.

Smallest positive zero of Weierstrass nowhere differentiable function
Quite a wealth of scholarly information here; thanks for your efforts, Dr. Renfro. Unfortunately, several users flagged this answer as either being excessively long or as not actually answering the precise question. If you could point out the parts that would either explicitly or in principle provide an answer to the precise question, that would surely address those concerns.
