Given a bounded set in the symplectic plane and a translation vector v=(a,b), the linear Hamiltonian H(x,y)=bx−ay generates translation by v. Multiplying it by a cutoff that equals one on the entire swept region produces a compactly supported Hamiltonian diffeomorphism that agrees with the translation on the set.
