> But I was interested in learning whether there was a LaTeX command like \DeclareMathOperator, except for binary relations (and which wasn't restricted to only being used in the preamble). Or maybe a pointer to some source about how LaTeX is told to interpret
symbols in math mode… I guess I need to return to the TeXbook.<br>
<br>
Look in the TeXbook p. 154, 170 etc or The LaTex Companion (2nd ed) pages 435, 525 and the tables thereof. In case you don't have access to these I attach the tables. In LaTeX you can also use \DeclareMathSymbol<br>
<br>
<rant> The most frequently encountered annoyance in mathematical typesetting I find in manuscripts and even in printed publications is the incorrect use of the | symbol i.e. not knowing the difference between \vert (or typing |) and say \mid. The second most
objectionable howler is… well I better stop here, I am already OT. </rant><br>
