= Moment equation

For a <Markov jump-process generator> $L$, differentiating an integrable observable gives $d\mathbb E[f(X_t)]/dt=\mathbb E[Lf(X_t)]$, when the generator identity and interchange are justified. Choosing powers gives equations for <moments>. These need not form a closed finite system.
