Suppose that $G, H$ are Lie groups and $\mathfrak{g}$ the Lie algebra of $G$. Suppose that there is a Lie group action $G \times H \to H$. Is there a natural $\mathfrak{g}$ action on $C^{\infty}(H)$? Thank you very much.

    $\begingroup$ Yes, by the vector fields of the associated Lie algebra action on $H$. $\endgroup$
