Abstract We consider two dimensional boson field theories with an interaction potentialV (φ). We show how to define a cut-off, renormalised Hamiltonian for a certain class of non-polynomialV (φ), which are defined via an integral transform. We formulate precisely a variational argument devised by Coleman, obtaining a constraint on the coupling constant of the theory with generalV (φ), and illustrate the argument with several examples.
