I have the problem with a symbol for symmetric difference (see http://en.wikipedia.org/wiki/Symmetric_difference). In commonly used is
\triangle
\ominus
But in Polish tradition often is used:
\dot{-}
and I would like to ask if it is possible to make dot be a little bit down to (close to) line (here where is the red dot).
Best Answer
I've shifted the dot down relative to
\dot{-}
. You may adjust the value of.2\LMex
to suit.EDITED to make it more robust and to achieve a more uniform vertical spacing at the smaller math styles.
