 Jan27 asked a 2 distance set has an upper bound for number of its elements Jan22 accepted $\lim_{n\to \infty}f(nx)=0$ implies $\lim_{x\to \infty}f(x)=0$ Jan21 asked $\lim_{n\to \infty}f(nx)=0$ implies $\lim_{x\to \infty}f(x)=0$ Jan20 comment limit of supremum of a sequence @JavaMan: Thanks. nothing is changed and now it looks more beautiful.

Jan4 asked Cayley-Hamilton theorem on square matrices Jan3 comment Sum of two Dedekind cuts is well-defined sorry if I don't know the rules of here since I'm new. I've added the homework tag, but since I reached nothing in solving it, I prefered not to touch the questions statement. please tell me if there is some other thing I must do.
