Jun 10	comment	What is a Hilbert space? Don’t worry, even Hilbert himself was wondering.
Jun 9	revised	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate made mistake visible
Jun 9	comment	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate Aaaand I found a mistake: $\Im (\alpha z) ≤ 1/\Im (z)$ only implies $\Im (\alpha z) ≠ \Im (z)$ for $\Im (z) > 1$.
Jun 9	answered	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate
Jun 8	comment	We need to Prove the existence or define a function on $[a, b]$ … e.g. take the Weierstraß function.
Jun 7	revised	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate added important piece of information
Jun 7	revised	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate re-edited question to contain my addition while removing unicode symbols
Jun 7	comment	Proving those elliptic matrices in $\operatorname{SL}_2(ℤ)$ are not conjugate @vadim123 What’s the problem with unicode?

Jun 6	comment	Suppose a,b are real numbers, if a is rational and ab is irrational, then b is irrational (Is my solution correct?) @GitGud What’s wrong with vimperator? Also, how are you rendering mathjax? Using SVG, right? As already told above, it works for me, too, when switching to SVG. You probably shouldn’t respond to this comment, as this gets too chatty. Now I upvoted your answer, because $-3$ seemed too harsh.
Jun 6	comment	Suppose a,b are real numbers, if a is rational and ab is irrational, then b is irrational (Is my solution correct?) @Git Gud : Me neither. Make a screenshot of how it’s supposed to look! Ah, it’s a thumbsup. I’m rendering with MathML, but using SVG it shows’s the thumbsup.
Jun 6	comment	Suppose a,b are real numbers, if a is rational and ab is irrational, then b is irrational (Is my solution correct?) The answer is Missingno.?
Jun 6	comment	Suppose a,b are real numbers, if a is rational and ab is irrational, then b is irrational (Is my solution correct?) Yes, it is, if you meant to prove that $b$ is ir-rational.
Jun 6	comment	Chinese Remainder Theorem and matrix Side question: How come CNT is an abbreviation for the Chinese Remainder Theorem?

Jun 6	comment	Chinese Remainder Theorem and matrix @robjohn He didn’t mention $(a, b, N) = 1$. It’s clear if you look into the paper.
