I have to type the product of n variables, $x_1\cdot\ldots\cdot x_n$
.
Although maybe this is semantically the right way (like it is for the sum), it doesn't look very well. What should be, typographically, a better way to do it?
For example:
Just the ldots as in $x_1\ldots x_n$
is confusing when there are going to be also lists of the variables separated by commas in nearby sentences.
With \dotsc
like in $x_1\dotsc x_n$
maybe, but is there a better idea?

Use
\cdots
. (See also:\vdots
and\ddots
.)Edit
Actually, I just read in the «Short Math Guide for LaTeX» by the AMS that:
\dotsc
is for dots with commas,\dotsb
is for dots with binary operators,\dotsm
is for multiplication dots,\dotsi
is for dots with integrals,\dotso
is for other dots.So,
\cdots
and\ldots
are commonly used but the AMS convention is to use the more semantic commands.
