Is there a way to do this? Currently I am using something like the following to do the job on scaling of a single letter in an equation:
\[
\int_{\Omega} (u - \text{\Large $\Pi_{\Omega}$} u) v \, dx = 0
\]
or
\[
\int_{\Omega} (u - \text{\scalebox{1.5}{$\Pi_{\Omega}$}} u) v \, dx = 0
\]
and as you can see, the \Omega
in the subscript of \Pi
is obviously bigger than the \Omega
as the domain of the integral sign:
I am curious if there is a way to manually adjust the size of the sub/sup-script of this resized letter? I tried using \scriptsize
and \scriptstyle
, both seem not working in mathmode
? or is there another solution for the rescaling/resizing other than exploiting \text{}
or \scalebox{}[]{}
. Thanks in advance!

The "large Pi" symbol you're looking for is called
\prod
(the analog of\sum
for products)The
\nolimits
is to avoid the subscript to go below the symbol in display style.If you need a smaller symbol in display style, you can define
and the result of
would be as follows
