Abstract: Let $ ({M_i},{\alpha _i})$, $ i = 1,2$, be two smooth manifolds equipped with symplectic, contact or volume forms $ {\alpha _i}$. We show that if a group isomorphism between the automorphism groups of $ {\alpha _i}$ is induced by a bijective map between $ {M_i}$, then this map must be a $ {C^\infty }$ diffeomorphism which exchanges the structures $ {\alpha _i}$. This generalizes a theorem of Takens.
