We find an explicit closed formula for thek’th iterated commutatorof arbitrary orderk⩾ 1 between a Hamiltonianand a conjugate operator, whereis the operator of multiplication with the real analytic functionωξwhich depends real analytically on the parameterξ, and the operatoris the operator of convolution with the (sufficiently nice) function, andvξis some vector field determined byωξ. Under certain assumptions, which are satisfied for the Yukawa potential, we then prove estimates of the formwhereCξis some constant which depends continuously onξ. The Hamiltonian is the fixed total momentum fiber Hamiltonian of an abstract two-body dispersive system and the work is inspired by a recent result [3] which, under conditions including estimates of the mentioned type, opens up for spectral deformation and analytic perturbation theory of embedded eigenvalues of finite multiplicity.
