I am looking for a way to define a new mathematical symbol, namely a lowercase pi, that will resize according to the font size of the surrounding text. The normal \pi
will not suffice as I am already using it to denote the constant 3.14... I am also using \varpi
for something else. I was thinking that a lowercase version of \varPi
, that is \scriptstyle \varPi
, would work. Basically, I want something like:
and so on. It is important that the lower case pi looks like \scriptstyle \varPi
because I am using it to denote a realization of a stochastic process denoted by \varPi
.
\varPi
to denote a stochastic process. So in my new article, where I also need to denote its realizations, I'm stuck with that choice.
