I am trying to represent the calculus of relations, from Tarski's paper. How do I represent the following following ? SideNote: I did go through http://math.mit.edu/~dspivak/files/symbols-all.pdf and https://www.rpi.edu/dept/arc/training/latex/LaTeX_symbols.pdf and anyother document I could find.


The only challenging one is the fourth in the list.



\langle \cdot,\bullet^{-},\cup,\mathbin{{\bullet}{\breve{\phantom{\imath}}}},1\rangle


Of course you want to make a new command for it.

  • Yes, I agree. May I know how you figured it out, other than years of practice and familiarity? Any references would be welcome. Dec 2 '18 at 17:38

    @GermanShepherd texdoc comprehensive from a terminl or texdoc.net/texmf-dist/doc/latex/comprehensive/symbols-a4.pdf For the complicated one, practice in solving similar problems.

  • Please, could you explain why did you use \mathbin?

  • @Sigur From the standard usages, I guess it is an operation symbol.

  • Ah, ok. I supposed it could be to get some appropriate positioning. So, the same for the 2nd one?!

I don't have the reputation to comment, but this website has been very helpful. It allows you to draw a symbol and it does a reverse search of Latex commands.
