\[\frac{d F(\boldsymbol{p}, t)}{d t}=\sum_{i, j} \frac{\partial}{\partial p_{i}} \int w_{i j}\left(\boldsymbol{p}, \boldsymbol{p}^{\prime}\right)\left(\frac{\partial}{\partial p_{j}}-\frac{\partial}{\partial p_{j}^{\prime}}\right) F(\boldsymbol{p}, t) F\left(\boldsymbol{p}^{\prime}, t\right) d \boldsymbol{p}^{\prime} .\]
