comment Algebra of Branch Cuts
There's nothing on the algebra of branch cuts in any other thread on here, the closest is this question but they never addressed the sum of branch cuts, let alone the algebra (arithmetic?) of this in general, could you remove the possible duplicate stuff?

comment Multivariate Taylor Expansion
Thanks man, the page works for me so if you can't access it just type "banach isomorphism multilinear", & maybe the word "toplinear" along with it, into google & you should get it - if not I'll type it all out explicitly for you.

comment Alternative function notation?
From wikipedia: "the term mapping, usually shortened to map, is either a synonym for function, or denotes a particular kind of function which is important in that branch, or denotes something conceptually similar to a function" ... "Some authors, such as Serge Lang, use "map" as a general term for an association of an element in the range with each element in the domain, and "function" only to refer to maps in which the range is a field." In other words, everybody is correct because it's just a matter of the way you set up your definitions.

comment How to prove that $\lim\limits_{n\to\infty} \frac{n!}{n^2}$ diverges to infinity?
$ \underset{n \rightarrow \infty}{\lim} \frac{n^2}{(n+1)} = \underset{n \rightarrow \infty}{\lim} \frac{\frac{1}{n}n^2}{\frac{1}{n}(n+1)} = \underset{n \rightarrow \infty}{\lim} \frac{n}{1+\frac{1}{n}} = \underset{n \rightarrow \infty}{\lim} \frac{1}{1+\frac{1}{n}}\cdot \underset{n \rightarrow \infty}{\lim} n = 1\cdot \infty = \infty$

comment Integration of Binomial Differentials Proof/Reference
Yeah the substitution direction is offered in Piskunov. Also on mathoverflow
