| contents | We present a novel extension of Moser's volume form lemma to the kinetic Liouville equation. In particular, we show that two smooth, positive phase-space densities $f$ and $g$ can be connected in unit time by the Liouville equation if and only if a natural compatibility condition on velocity marginals is satisfied. Under this condition, an explicit family of force fields is constructed via a weighted elliptic problem in the velocity variable. Results of numerical experiments are presented to validate the theoretical framework. |
