May 17	comment	Does there exist a smooth function which is nowhere analytic? Your example is not analytic only at one point.

Apr 23	comment	An application of contraction mapping theorem I tried to edit it, but this edit is too short.

Apr 23	comment	An application of contraction mapping theorem What if I write it as $\frac{1}{3}\|x-y\|\left\|\frac{x+y}{(1/3+x^2)(1/3+y^2)} \right\|$, do I get the bound then?

Apr 23	comment	An application of contraction mapping theorem I think I found it, is it just 1? For $x,y\geq 1$, $x+y$ is always smaller than $1+3x^2+3y^2+9x^2y^2$...

Apr 17	comment	What does $a^b$ mean? I just want to know if there is any deeper reason behind this notation, because it is really confusing to me.
Apr 17	comment	What does $a^b$ mean? @Abel, yes maybe it is subjective, but, in your example of matrix addition or multiplication, in the end it still boils down to adding and multiplying field elements, whereas complex exponentiation seems much more different from discrete one. This is all my opinion, of course.
