# Letter with circle above — not a dot — in math mode [duplicate]

I need to typeset letter with a circle above it in math. \dot A does a very close result, but I need something that looks like \circ, not like \cdot.

Edit: there is awesome answer here, but Detexify failed for me, and I tried looking up tables, but haven't found what I needed.

• \mathring{A}. – Manuel Apr 30 '15 at 8:33
• I was not thinking of detexify, but of texdoc symbols given as the first option in the top answer - table 164 Math mode accents, the same table containg \dot. That not only answers your question, but tells you how to find answers to similar questions. – Andrew Swann Apr 30 '15 at 9:59
Use \overset{\circ}{X} or \mathring{X} for letter X say

• \mathring - exactly what i needed! – Lapshin Dmitry Apr 30 '15 at 8:55
• I'd avoid the first: \mathring is the correct answer – egreg Apr 30 '15 at 9:22
