I want to have a function name (like g(.)) and I do this in this ways:

  1. $g \left( . \right)$
  2. $g(.)$

But in either way, the dot "." seems a little lower than it is better to be. I am wondering if there is another way to have this output? (this may seem so basic but when I saw that writing three consecutive dots has its own command, I doubted may be I am doing it wrong)

  • Yeah, definitely it is better. I appreciate it. Commented Dec 18, 2010 at 7:04
  • The Wikipedia page for Interpunct contains some helpful LaTeX commands. Commented Feb 4, 2019 at 12:38

Use \cdot for a single vertically centred dot.


In text (non-mathematical) context, the symbol you may be looking for is \textbullet. I mention this here because people Google-searching for this answer will likely find this page is result #2, as I did, with no more relevant results above it.

    Thanks. since no context is defined in the question, actually this should be the answer ;) Commented Oct 25, 2015 at 8:56

    \textbullet (in text mode) and \cdot (in math mode) look pretty different; the former is much heavier. If you want a light dot, one option is just to write $\cdot$, of course. Alternatively, maybe look here or here. Interpunct on Wikipedia maybe also useful for tracking down the symbol you want. Commented Jun 8, 2023 at 1:45

You can use \mathord{\cdot} for a centered dot with symbol-like (rather than binary operation-like) spacing.
