SUMMARY

The discussion focuses on the notation for iterated integrals, particularly in the context of multiple dimensions. Users propose using a single integral sign accompanied by specific measures to indicate the dimensionality of the integral. For example, a volume integral in n dimensions can be represented with one integral sign while clarifying the dimensionality through the measure. The notation for hypersurface integrals is similarly addressed, emphasizing the use of a single symbol for clarity in higher dimensions.

PREREQUISITES

Is there some notation for an iterated integral, like there is for summations and products?

e.g.

\overset{m}{\underset{n=0}{\raisebox{-0.07in}{\Huge{\texttt{I}}}}} f(x_0,x_1,x_2,\ldots,x_m) dx_n

\overset{m}{\underset{n=0}{\raisebox{-0.07in}{\Huge{\texttt{I}}}^{b}_{a}}} f(x_0,x_1,x_2,\ldots,x_m) dx_n

Here I have used "I" to stand in for whatever the correct symbol might be...

Thanks in advance.

If the integral is a volume integral in "n" dimensions (n>=3), then one can put only one integral sign, but specify the fact that the integration is not in one dimension (as one could assume, once he sees only one symbol of integration) through the measure. In this case a volume integral is an iterated integral. Treating hypersurface integrals is not any different, as one could use only one symbol, even if the # of dimensions is not 1.
 
So for a 'hypercubic volume integral' over 0 ... 1 in m dimensions, I could do:

V = \prod^{m}_{n=0} [0,1]

\int_V f(x_0,x_1,x_2,\ldots,x_m) dV

Thanks.
