   Format: MarkdownItexWith the recent activity on Banach spaces, now seems like a good time to remind people that iTeX renders the spacing around norms and absolute values much better if you put braces around them. (Also include subscripts, superscripts, and `\left`/`\right` commands inside the braces.) Thus `\|x\|^2 + \|y\|^2` produces $\|x\|^2 + \|y\|^2$, while `{\|x\|^2} + {\|y\|^2}` produces ${\|x\|^2} + {\|y\|^2}$.

   Thus \|x\|^2 + \|y\|^2 produces $\parallel x{\parallel }^2+\parallel y{\parallel }^2$, while {\|x\|^2} + {\|y\|^2} produces $\parallel x{\parallel }^2+\parallel y{\parallel }^2$.

   Format: MarkdownItexThanks -- I couldn't remember the trick (although I could have remembered where to look had I thought harder about it).

   Format: MarkdownItexI'm a frequent offender as well. I knew that there was something to do with placement of braces, but couldn't remember what it was.
