Hi, I have in a previous thread discussed the case where:
\begin{equation}
TT' = T'T
\end{equation}
and someone, said that this was a case of non-linear operators. Evidently, they commute, so their commutator is zero and therefore they can be measured at the same time. What makes them however non-linear?
Thanks!
