In mathematics, the Liouvillian is another expression for the Liouville differential operator given by the mathematical expression:
![{\hat{L}}=\sum_{i=1}^{N}\left[ \frac{\partial H}{\partial p_{i}} \frac{\partial }{\partial q_{i}}-\frac{\partial H}{\partial q_{i}}\frac{\partial }{\partial p_{i}}\right].](a/../upload/math/3cac1ab33461ad7193bc17d217212c89.png)
