Miscellaneous

Some useful LaTeX tips that make a huge difference (thanks in particular to Rik Voorhaar, Karel Kolar, Lukas Konecny, Jimmy Found, Igor Khavkine, Samuel Valach, Mark Bugden):

• when using beamer, put \beamertemplatenavigationsymbolsempty to get rid of the "navigation bar"

• use \colon when writing f: A → B

• to get correct spacing, when writing abbreviations (J. Smith, e.g., etc.) use J.\ Smith

• for (simple) graphics, use tikz

• you can often avoid using braces, e.g. \expression abc instead of \expression{a}{b}{c}

• \frac12 instead of \frac{1}{2} (since numbers are never interpreted as part of LaTeX macros)

• \mid for the vertical line in the set-builder notation (e.g. \{ n^3 \mid n \in \mathbb N \})

• use \DeclareMathOperator for operators like im, ker, sup, ... (makes better spacing than \mathrm)

• use Detexify to find out how to write a particular symbol

• mhchem for chemical formulas

• \tfrac (textstyle fraction) is often more appropriate than \frac (the opposite command is \dfrac)

• \hphantom{text} (and \vphantom) to get the right spacing

• when splitting \left( ... \right) into 2 lines, use \right. at the end of the 1st line and \left. at the start of 2nd
