<disclaimer>Not a mathematician, but took enough Ph.D. level classes to be dangerous with bad proofs.</disclaimer> > Using a set of unwritten naming rules Simplest being things like using upper case Greek for certain sets and lower case Greek for its elements. Or, in Statistics, using Greek letters for parameters and English equivalents for their estimates. So, if I were programming something to do something in that realm, I would write: for my $ω ($Ω) { # ... } where what Ω represents would be clear from the subfield of Math that is relevant to the program. Then, of course, you get people like one of my former professors who liked to invent notation on the fly and would quickly and up cycling through Greek (π, Π), Hebrew (פ), Blackboard (ℙ), and reach out for Sanskrit (?). (Symbols used here for illustration, this was a long time ago and we didn't even know if he was correct as we had no way of checking with no intarwebs back then.)
