I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

@tohecz I advocate more “semantic” names for personal macros; maybe less easy to type, but surely more readable.

You tag this with titlesec; if you're exploiting this package, we need to know how.

@StevenB.Segletes You need \relax before \ifmmode, not an additional pair of braces. Better yet, \DeclareRobustCommand should be used (which would make \relax redundant).

comment \varepsilon vs. \epsilon
In my copy of Kelley's “General Topology”, ‘ɛ’ (not lunate) is used for “belongs to”. I think the lunate one is used in the book for cases like “let ϵ > 0”, which is not so good a notation, in my opinion. That's why the vast majority of mathematicians use a clearly distinct variant ‘∈’ of the lunate epsilon for denoting “belongs to” (bigger, wider and centered to the formula axis).

@StevenB.Segletes Yes there are drawbacks; \L is a macro belonging to the LICR, and should not be redefined.

Welcome to TeX.SX! While \L may seem a good shortcut, it's better avoiding different meanings of the same macro depending on the context.

@Tangshutao You're welcome. I know no Chinese, but some LaTeX. ;-)

comment Why do the labels in the PDF file become garbage characters?
I get no garbage, but introduction, changzhou and conclusion in the bookmarks. Please, note that spaces are significant, so you should type \end{document} (no spaces inside) and similarly for the other places.

comment How can I use German umlauts in DeclareMathOperator?
@Manuel Yes, it's a problem with fontspec; kerning is not applied. I think it's something that should be fixed, but it surely requires interaction with amsmath.

@Vincent Such a numbering will only confuse your readers.

@moose There is no reason for using \textnormal in general.
