You should include "finite-dimensional" somewhere in that sentence. The Lie algebra $\mathbb R$ acts on $\mathcal C^\infty(I)$, where $I$ denotes the open unit interval $I = (0,1)$, by sending the basis vector to $\frac{\partial}{\partial x}$, but this representation is not integrable to a representation of $\mathbb R$ on $\mathcal C^\infty(I)$. | |
