Interior of a set notation
11
I'm trying to match this:
I've already tried (in amsmath)
$A^0$
$A^o$
$A^circ$
None of these match the above image however.

Welcome to TeX.SX! It could be$A^{mathrm{o}}$. Can you add a source for such a notation?

Unfortunately with that the circle is too low, but definitely matches it better than the others (but not perfectly). As for a source, the image was taken from a scan. (I would like to confirm that I am user99133 but had somehow managed to post under a guest account)

font differences are to be expected, but what is the intended meaning, is that an index 0 or a superscipt O when taken in context?

It's the interior of the set A, usually seen in topology. The index is much closer to an o rather than a 0. As for font differences, I understand that but would like to match it as close as possible.

The symbol seems to be an upright “o”; in order to raise it more than it would be with $A^{mathrm{o}}$, you can define a macro.

newcommand{interior}[1]{%
{kern0pt#1}^{mathrm{o}}%

Above all, use a macro, that way you can change it later (or even provide it with a few intelligence), here's a basic version
newcommand*interior[1]{#1^{mathsf{o}}}
You can let interior be intelligent, and do (#1)^{mathsf{o}} in case there are a few symbols inside, or even some parenthesis above the whole expression like some notations do.

Above all, use a macro, that way you can change it later (or even provide it with a few intelligence), here's a basic version
newcommand*interior[1]{#1^{mathsf{o}}}
You can let interior be intelligent, and do (#1)^{mathsf{o}} in case there are a few symbols inside, or even some parenthesis above the whole expression like some notations do.

Welcome to TeX.SX! It could be
$A^{mathrm{o}}$. Can you add a source for such a notation?– egreg

Unfortunately with that the circle is too low, but definitely matches it better than the others (but not perfectly). As for a source, the image was taken from a scan. (I would like to confirm that I am user99133 but had somehow managed to post under a guest account)

font differences are to be expected, but what is the intended meaning, is that an index 0 or a superscipt O when taken in context?

It's the interior of the set A, usually seen in topology. The index is much closer to an o rather than a 0. As for font differences, I understand that but would like to match it as close as possible.

wikipedia suggests that it is ^o with a lowercase o en.wikipedia.org/wiki/Interior_%28topology%29
