Correct notation
In Santaló's formula, I took the liberty of changing the first form below to the third. Either the second or the third may be considered standard notation. The code in the first is \backslash, in the second is \setminus, and in the third is \smallsetminus.

\begin{align} \text{wrong: } & SM\backslash\partial_0 SM \\[6pt] \text{right: } & SM\setminus\partial_0 SM \\[6pt] \text{right: } & SM\smallsetminus \partial_0 SM \end{align} $$ The difference between the first two is not merely that there is some space to the left and right of the binary operation symbol; rather, when the second form or the third is used, the amount of space to the left and right of that symbol depends on the context.
