Abstract

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