# vertically centered dot

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)

I changed the title to better match the question. I hope the new title fits with your intention. –  Caramdir Dec 17 '10 at 17:52
Yeah, definitely it is better. I appreciate it. –  Yasser Sobhdel Dec 18 '10 at 7:04
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.
