I'm trying to perform the plethystic substitution $f \rightarrow f[\frac{X}{1-q}]$ (which is given by $ f[\frac{X}{1-q}] = f(x_1,qx_1,q^2x_1,...,x_2,qx_2,...)$)
I tried to implement this in Sage using the command .plethysm(X/(1-q)), but it doesn't seem to be giving me the right thing (I have no idea how it's interpreting 1/(1-q) actually). Does anyone know if this is implemented, and if so, how to get it to work?
Thanks so much in advance!Tue, 06 Apr 2021 08:07:49 +0200https://ask.sagemath.org/question/56514/x1-q-plethystic-substitution/Comment by slelievre for <p>Hello everyone!</p>
