Abstract
It is shown that the wave operators which can be introduced in quantum field theories with cutoff interactions can be represented by wave transformers acting on states represented by statistical operators. Integral representations can be found for these wave transformers, which then form the basis of a time-independent scattering theory for such quantum field theories. It is pointed out that this leads to a time-independent perturbation theory in Fock space.Keywords
