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. – Yasser Sobhdel Dec 18 '10 at 7:04
  • The Wikipedia page for Interpunct contains some helpful LaTeX commands. – user146829 Feb 4 '19 at 12:38

Use \cdot for a single vertically centred dot.

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

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 ;) – Yasser Sobhdel Oct 25 '15 at 8:56
